It's All Fun and Games Until Someone Looses Their Underwear....

The friendship between Britney Spears and Paris Hilton was short, sweet and photogenic. But now, it seems, it's over. A source close to Spears explains why the pop tart, who lost her undies last week, has not been seen with her "new best friend" Hilton since she posted an apology to her fans on her Web site, noting, "Thank God for Victoria's Secret underwear!" The source said, "Britney has been told by her people that if she ever wants a comeback, she has to stay far away from Paris and start acting like an adult."
