The hotel heiress has hit headlines in recent weeks as she soaks up the sun in St. Tropez, France with Jho Low and a group of pals.
Hilton has been seen swigging from bottles of champagne and partying on a yacht with the tycoon as she spends her summer relaxing in Europe, sparking speculation she's receiving a hefty pay cheque to liven up Jho Low's holiday.
But a rep for the star is adamant the stories are not true, telling New York Post gossip column Page Six, "They are friends. Jho has invited Paris and her sister, Nicky, out to St. Tropez as friends. He has not paid her in any way, although he is extremely generous."
The socialite-turned-fashion designer has been dating TV producer David Katzenberg since 2006 and she was forced to deny rumours they were set to exchange vows in 2008.
But the claims refuse to go away and Hilton has now brushed off fresh reports suggesting the couple is preparing to walk down the aisle.
She tells U.S. tabloid Star, "There are no wedding plans in the works."
Hilton was previously married to businessman Todd Andrew Meister, but their union was annulled in 2004, shortly after they tied the knot in a Las Vegas wedding.
The socialite was photographed locking lips with actor Paul Iacono, who stars as a well-endowed teen in David Katzenberg's new TV project The Hard Times of RJ Berger.
A party guest says, "We thought it was a publicity stunt at first, but Paris was really making out with this guy."
And Paris, whose sister Nicky is Katzenberg's longtime girlfriend, has fuelled speculation that the young actor is her new man with a post on her Twitter.com blog.
She writes, "My new boy toy is hot," and links to a picture story about her night of passion with Iacono.
If the romance is for real, the young actor will be the socialite's first boyfriend since she split from reality TV star Doug Reinhardt in April (10).
Oil heir Davis proposed to his longtime girlfriend Michelle Haugo on Tuesday (01Jun10) after successfully kicking his heroin addiction during a 30-day stay at a drug rehabilitation centre, and Hilton and her designer sister Nicky have been invited to join the bridal party.
His representative, Brian Quintana, tells the New York Post's gossip column Page Six, "Jason has been clean for a month and celebrated by asking Michelle to marry him. He has asked his old friends Paris and Nicky Hilton to be bridesmaids."
The socialite planned to fly to Nice, France to join her sister Nicky and brother Barron for the start of the glamorous festivities.
But she was forced to delay her trip when she realised she didn't have her passport with her, reports New York Post's gossip column PageSix.
Nicky Hilton was later reportedly overheard telling fellow revellers in Cannes, "She had to turn around and get another flight."
But Paris managed to fly in to France to join her family for the Monaco Grand Prix at the weekend (15-16May10) - and has since been photographed partying in Cannes.
The socialite was spotted enjoying a night out in Las Vegas on Saturday (11Apr10) with her sister Nicky and Kim Kardashian's ex-boyfriend, footballer Reggie Bush.
According to reports, Hilton was in Sin City with her family after splitting from her boyfriend of 14 months, while Reinhardt had fled to Aspen, Colorado with his father.
A source told E! Online, "Obviously she broke up with him."
But Hilton has silenced the speculation with a post on her Twitter page, writing, "Can't a girl have a night out in Las Vegas with her sister, without fake stories being posted. That story is a ridiculous lie. 100 per cent FALSE."
Sharon Osbourne, Rupert Grint and Tyra Banks have also raided their closets to support the Give Up Clothes for Good campaign, to raise money for Cancer Research U.K.
Banks has offered up a Catherine Malandrino dress and Osbourne has donated a Burberry coat, while funnyman Walliams has parted with a Tom Ford suit.
He says, "While I would have loved to keep it, I know it will be raising money for an important cause. Cancer is such a horrible disease at any age, let alone when you’re a child, so we need to do everything we can to help fund more research. Please take part in this campaign and help save more lives.”
The sale starts on website eBay.com on Thursday (25Mar10) and will run for one week.
The socialite-turned-fashion designer has been dating TV producer David Katzenberg since 2006. They became involved two years after her marriage to businessman Todd Andrew Meister was annulled shortly after their Las Vegas wedding.
Hilton dismissed rumours of an engagement to Katzenberg in 2008, but her boyfriend is now said to be preparing to make their union official, according to New York Post gossip column Page Six.
A source tells the newspaper, "Obviously, David would never propose around Oscar time. But now that awards season is over, everyone thinks he'll ask her soon."
Socialite PARIS HILTON capped off a week of birthday celebrations with a big bash at her Hollywood home on Friday (26Feb10). The 29 year old partied the night away with her boyfriend Doug Reinhardt, designer sister Nicky Hilton, Heroes star Hayden Panettiere and actor Brandon Davis. Hilton turned 29 on 17 February (10).
The Johnson & Johnson heiress was buried at a private ceremony hosted by her dad, Robert Johnson, the owner of the New York Jets American football team.
Her fiancee, reality star Tila Tequila, was not present among the mourners, reports RadarOnline.com.
Johnson was found dead at her Los Angeles home on 4 January (10) at the age of 30.
An autopsy showed there were no signs of trauma, but the cause of death has been deferred, pending toxicology tests.
