The new year began with wedding bells for many couples including singer Shania Twain, who married her fiance Frederic Thiebaud in Puerto Rico on New Year's Day, while country star Kellie Pickler and actress Valerie Bertinelli also walked down the aisle on 1 January.
The new year brought baby news for a number of celebrity couples - Orlando Bloom and his wife Miranda Kerr became first-time parents with the birth of their son Flynn. Penelope Cruz and Javier Bardem also welcomed a son, and Owen Wilson became a father just days after he announced his girlfriend's pregnancy. Nicole Kidman also hit headlines when she and her husband Keith Urban revealed they welcomed a daughter called Faith via a surrogate mother over the holidays.
There was also pregnancy news for actress Kate Hudson, who announced she was expecting a baby with Muse rocker Matt Bellamy, as well as Marion Cotillard, Jewel, Selma Blair and Victoria Beckham, who confirmed she was pregnant with her fourth child.
However, the first few weeks of 2011 also brought a slew of celebrity splits - Keira Knightley ended her longtime romance with actor Rupert Friend, Shakira parted ways with Antonio de la Rua, her boyfriend of more than 10 years, and Mila Kunis and Macaulay Culkin separated after eight years together.
Many stars saw in the new year by addressing their personal problems, and a number of famous faces went in and out of rehab in the first few weeks of 2011. Lindsay Lohan and Demi Lovato both ended long treatment stints in January, while David Arquette, Backstreet Boys star A.J. McLean and his bandmate Nick Carter's younger brother Aaron all enrolled in programs. Troubled actor Charlie Sheen also admitted himself to a clinic just weeks after he was hospitalised to treat a hernia, and he later admitted he turned to booze to blot out the pain of the medical condition. Sheen’s rehab stint forced TV bosses to shut down production on his show Two and a Half Men.
Another colourful character to hit the headlines in January was British funnyman Ricky Gervais, who managed to cause controversy during his stint as Golden Globes host. The comedian was condemned by organisers for poking fun at celebrity guests including Robert Downey, Jr., Johnny Depp and Tom Hanks during the glitzy prizegiving.
The month held good news for veteran actor Michael Douglas as he was given the all-clear after a gruelling battle with throat cancer. His wife Catherine Zeta-Jones subsequently admitted she cried tears of joy when doctors told the couple the actor had beaten the disease. Poison rocker Bret Michaels also overcame a health crisis after undergoing successful surgery to close a hole in his heart.

As awards season got into full swing, The King's Speech was the toast of Hollywood after scooping four Oscars including Best Picture, Best Actor for the movie's star, Colin Firth, and Best Director for Tom Hooper, while Natalie Portman fought back tears as she walked away with the Best Actress honour for her role as a tormented ballet dancer in Black Swan. It was a different story at the Independent Spirit Awards, where Black Swan trounced its rivals, picking up four honours including Best Director for Darren Aronofsky.
In the world of music, Lady Gaga's incredible rise continued as she picked up three Grammy Awards, including Best Pop Vocal Album, but her achievements were overshadowed by country trio Lady Antebellum, who scored five accolades, and the shock win for Canadian rockers Arcade Fire in the prestigious Album of the Year category for their disc The Suburbs. Across the pond at the Brit Awards in London, Arcade Fire were again bathed in glory when they were handed the International Group and International Album honours, while newcomer Tinie Tempah crowned a triumphant 12 months by taking home the British Breakthrough Act and British Single titles. Rihanna was named Best International Female solo star, and Justin Bieber was named the International Breakthrough Act of the year.
Away from the red carpet, it was a bleak month for My Name Is Earl actress Jaime Pressly, who was charged with driving under the influence after failing a field sobriety test, Dirty Dancing star Jennifer Grey, who was underwent an operation to remove a growth from her foot, Slayer guitarist Jeff Hanneman, who was hospitalised with a flesh-eating bug, and Dame Judi Dench, who broke two of her toes on the set of her new movie J. Edgar.
There were also woes for Rihanna, whose raunchy promo film for single S&M provoked outrage around the world and was banned in 11 countries, actress Eliza Dushku, who broke a finger on holiday, and fashion king John Galliano, who was suspended and later sacked by Christian Dior after he was filmed launching an anti-Semitic rant at stunned drinkers in a bar in Paris, France.
Rock duo the White Stripes stunned the music world when they announced they were splitting up after 14 years, and Lady Gaga's much-hyped new single Born This Way was unveiled to a barrage of accusations she had ripped off Madonna's classic Express Yourself. But there was good news for older music fans, as '60s icons The Monkees announced they were reuniting for a U.K. tour.
Loved up celebrity couples Justin Bieber and Selena Gomez, and Anna Friel and Rhys Ifans, both confirmed their engagements, and there were wedding bells for Kelsey Grammer - who married for the fourth time - and Mark Ronson and Katherine Jenkins, who both announced their respective engagements.
Among the stars hearing the pitter-patter of tiny feet this month were Christina Applegate, who gave birth to a daughter, magician David Blaine, who became a first-time father to a baby girl, reggae star Zac Marley, rocker Rod Stewart, Sex and the City's Cynthia Nixon, and No Doubt star Tom Dumont.
Jude Law continued his unlucky-in-love streak when he split - yet again - from Sienna Miller, Iron Man star Terrence Howard was hit with divorce papers, Olivia Wilde split from her husband after eight years, and celebrity couple Ashlee Simpson and Pete Wentz announced their marriage was over.
The world of showbiz bid farewell to guitar legend Gary Moore, who died aged 58, blues legend Eddie Kirkland died in a car crash at the age of 88, Seinfeld star Len Lesser succumbed to pneumonia aged 88, and The Dukes of Hazzard actress Peggy Rea, who passed away at the age of 89.
Tinseltown lost one of its brightest lights in March after movie icon Dame Elizabeth Taylor died of congestive heart failure at the age of 79. Tributes from the world of showbiz poured in for the Cleopatra legend, with Sir Elton John, Jane Fonda, Barbra Streisand and Liza Minnelli leading the heartfelt remembrances. The acting great was interred at Forest Lawn Memorial Park in Glendale, California, where her dear friend Michael Jackson was also laid to rest in 2009.
March was also marked by controversy as a host of famous faces found themselves in the headlines for all the wrong reasons.
Pop star Christina Aguilera was arrested for drunkenness in West Hollywood, while Boardwalk Empire beauty Pas de la Huerta was also apprehended after a bar fight in New York City. Jackass daredevil Steve-O was taken into custody in Canada on an outstanding warrant, and rapper Rick Ross got caught smoking marijuana in a Louisiana hotel room.
But it was Charlie Sheen who really gave fans something to talk about after he was fired from Two and a Half Men following months of public feuding with writer/creator Chuck Lorre. Days later, cops raided Sheen's Los Angeles home to investigate a tip that the troubled star was in violation of a court order by keeping a gun in the house.
March also brought one of the year's most devastating tragedies as Japan was hit by a massive earthquake, which then created an enormous tidal wave. More than 15,000 people perished in the disaster and Slash, Lady Gaga, the Black Eyed Peas and the Foo Fighters were among the big-name acts who staged gigs to raise money for victims, while actresses Sandra Bullock and Demi Lovato also donated $1 million (£625,000) each to boost relief efforts.
Back in Hollywood, there was plenty of heartache as Justin Timberlake and Jessica Biel ended their romance, Renee Zellweger called it quits with Bradley Cooper and Twilight beauty Ashley Greene split from Joe Jonas.

There were births, marriages and bust-ups galore as Spring sprung in April (11), but only one subject was on everyone's lips - the royal wedding. Celebs and commoners alike got carried away in the buzz of the big day on 29 April, when brunette beauty Kate Middleton walked down the aisle with her very own Prince Charming, William. Who would design the dress? Who would be invited? Would best man Harry fall for bridesmaid Pippa? But all questions fell by the wayside on the morning of the magical day, as Britain and two billion viewers across the world came to a standstill to watch the future Queen of England step out of her Rolls-Royce wearing a stunning Alexander McQueen lace gown to huge cheers from the crowd. The pair wed in front of 1,900 quests, including Queen Elizabeth II, the entire royal family, and even showbiz royalty Victoria and David Beckham, and left London's Westminster Abbey to great fanfare as the new Duke and Duchess of Cambridge. But Kate didn't hog all the limelight - who can forget the backing support of her sister Pippa, hailed Her Royal Hotness thanks to that figure-hugging dress and her much-discussed derriere?
The wedding was of fairytale proportions, one even our favourite celebs couldn't compete with - but that didn’t stop them from trying! Canadian crooner Michael Buble was one of the biggest stars to walk down the aisle in April (11) - his second set of nuptials to stunning fiancee Luisana Lopilato following their original wedding day in March (11). Controversial couple LeAnn Rimes and Eddie Cibrian also wed in a private ceremony in Malibu, which was a surprise for guests - they thought they were there for the pair's engagement party! Funnyman Rob Schneider also joined the marriage club, exchanging vows with fiancee Patricia Azarcoya Arce over the Easter Weekend. The marriage mood of the month gave many stars ideas; the likes of Kate Hudson and Matt Bellamy, and Tom Fletcher and his longtime girlfriend became engaged.
Despite love being in the air, some unions were destined to end - Elizabeth Hurley started divorce proceedings against her millionaire husband Arun Nayar, while Christina Aguilera's five-year marriage to Jordan Bratman was declared officially over. After marriage must come babies, and April was awash with stars welcoming newborns. Superstar Mariah Carey welcomed twins Moroccan and Monroe, and in true diva style, gave birth to them on her fourth wedding anniversary to Nick Cannon. The Killers frontman Brandon Flowers and Black Eyed Peas rapper Taboo both welcomed their third sons, while Jane Krakowski, Kevin James, Toni Collette and Drea De Matteo all also became parents to baby boys. Mexican actor Gael Garcia Bernal was an exception to the rule - he became the proud father of a baby girl.
But with ups, there must be downs - and nobody does scandal like the stars. Teen sensation Demi Lovato stunned her legions of loyal fans by opening up about the emotional issues which landed her in rehab earlier in the year, revealing she was battling an eating disorder and cut herself at her lowest moments. Charlie Sheen continued his madcap ways by embarking on a comedy tour following his sacking from Two and a Half Men - only to get booed offstage on his first night, with critics calling his stand-up debut an "epic failure". Bond fans mourned April as the month Sir Sean Connery announced he was retiring from public appearances after he failed to show up to a charity event in New York. Lindsay Lohan was back in trouble - and in court - when a judge decided she'd had enough of the actress' antics and sentenced her to 120 days behind bars for violating her probation. Nicolas Cage hit the headlines when he was arrested on domestic violence charges following a street bust-up with his wife in New Orleans, and Vince Neil was also in hot water for domestic violence - his ex-girlfriend accused him of jabbing a finger at her during an argument. However, the biggest shock came when Welsh beauty Catherine Zeta-Jones checked into a mental health facility to overcome her bipolar disorder. The stint in the clinic came after a tough year for the Oscar-winner following husband Michael Douglas' cancer battle.
April was a sad month for actor Tim Robbins, who tragically lost his father, Gil, and his mother, Mary, within days of each other. The punk world was left in mourning when X-Ray Spex legend Poly Styrene lost her battle with cancer at the age of 53, while British actress Elisabeth Sladen, Dr Who's longest running sidekick, also passed away after a fight with the disease.
May was a shocking month as Hollywood tough guy Arnold Schwarzenegger split from his wife of 25 years Maria Shriver, only to reveal later on in the month he had fathered a lovechild with their housekeeper 13 years earlier. Although the scandal rocked Hollywood, he wasn't the only one heading for splitsville - Charlie Sheen and Brooke Mueller became officially divorced, as did actress Neve Campbell and James Bond star George Lazenby. Lady Gaga also split from boyfriend Luc Carl, while Hayden Panettiere ended her romance with her boxer boyfriend Wladimir Klitschko.

British rocker Pete Doherty was also jailed for six months for cocaine possession. Other stars facing woes included Amy Winehouse, Whitney Houston, Friends star Matthew Perry and boxer/singer Oscar De La Hoya, who were all submitted in to rehab programs.
