Britney makes marriage official, drops manager

Pop princess Britney Spears formalized her union with dancer Kevin Federline on Thursday, filing for a marriage license, Reuters reports. As Spears, 22, and Federline, 26, exchanged vows in a secret wedding ceremony in Los Angeles last month, rival tabloid magazines reported the marriage may have been fake. Spears acknowledged then that the couple had yet to file a marriage license–as California law requires within 90 days of the ceremony–but insisted their wedding was real. “All the proper paperwork was dealt with [Thursday], filed, done. It’s all legal,” Spears‘ publicist, Leslie Sloane, told Reuters. At the same time she finalized her nuptials, Spears also split with her longtime manager, Larry Rudolph, who announced Thursday that he and the singer had “mutually agreed not to renew their nine-year management relationship.” Rudolph is credited with discovering the Louisiana native when she was just 13 years old, helping guide her early career and building her into one of the most successful recording stars in recent years. In a statement, Rudolph said, “Britney and I simply realized what we have done all we can do together.”

Stewart reports to jail

Homemaking guru Martha Stewart arrived at a minimum-security prison in Alderson, West Virginia, known as “Camp Cupcake” in the wee hours of the morning Friday to begin her five-month sentence, Reuters reports. Stewart told her fans through her Web site, “By the time you read this, I will have reported to…begin serving my five-month sentence.” The former chief executive of Martha Stewart Living Omnimedia, who vows to make a comeback, was found guilty in March of conspiracy, making false statements and obstruction of justice–all stemming from her suspicious sale of stock in biotech firm ImClone Systems Inc. on Dec. 27, 2001.

Etheridge diagnosed with cancer

Rocker Melissa Etheridge has been diagnosed with breast cancer and has canceled upcoming tour dates to undergo treatment, The Associated Press reports. Etheridge, 43, will undergo surgery and her doctor expects a “speedy and complete recovery,” publicist Marcel Pariseau said in a statement, after detecting the cancer early. “I am fortunate to be under a wonderful doctor’s care and thankful that this was caught early,” Etheridge said in the statement. “I am looking forward to a quick and full recovery.”

Kidman causes a stir at Paris fashion show

Chaos erupted on the Paris catwalk on Friday as Nicole Kidman arrived to launch her promotional campaign for Chanel’s legendary No 5 perfume, AP reports. Kidman was there to shoot a two-minute film, directed by her good friend Baz Luhrmann, in which she plays an actress who flees photographers at a movie premiere and ends up romancing a handsome stranger, played by Brazilian actor Rodrigo Santoro. Designer Karl Lagerfeld created a red-carpeted runway for Friday’s show to mimic the campaign, and life promptly imitated art as photographers swarmed in to get a shot of Kidman. “I thought he made it really fun and vibrant,” Kidman said backstage after the show. Chanel is hoping the advertising blitz will help it win the battle for the all-important Christmas perfume market.

Thornton gets star on Walk of Fame

Oscar-winner Billy Bob Thornton got his very own star on Hollywood’s Walk of Fame Thursday, AP reports, as well as a special message from ex-wife Angelina Jolie in a full-page Variety ad: “Billy, I love your brilliant mind…Congratulations! With love and respect always, Angie.” Joked Thornton to AP Television News: “You know, it’s funny….I’ve only met Angie Dickinson once.” But the 49-year-old actor was modest about the honor. “You can try to be humble about this kind of thing and say, ‘Oh well, it’s fine or whatever,'” Thornton told the crowd. “But the fact of the matter is it’s a huge honor and I appreciate it so much.”

Incubus singer detained at NY airport

Brandon Boyd, the lead singer of the rock band Incubus, was arrested Wednesday at LaGuardia Airport after carrying a switchblade in his bag, AP reports. Boyd, who was on his way to a concert gig in North Carolina, was charged with criminal possession of a weapon but was able to continue his travels in time for the concert, a spokeswoman for the band’s label, Epic Records, told AP. Boyd admitted he accidentally left the knife in his bag and called the incident “my bad,” spokeswoman Lois Najarian said. “I totally forgot it was at the bottom of my bag, and when the security person pulled it out, I thought, ‘Oh, no,'” Boyd said in a statement Thursday.
