I couldn't make this stuff up, people. According to Us, just before 1 am on Nov. 18, Britney Spears threw a hissy fit at Hustler's West Hollywood boutique when staffers told her she couldn't try on a selection of risqué undies. (Shouldn't they have been applauding her interest in wearing drawers in the first place?) In response, the singer, who was described as being out of it, dropped trou in front of more than a dozen other shoppers, and squeezed into a pair of boy shorts. "The employees kept saying, 'Don't change out here!'" a mag source recalls. "She's like, 'Well, I couldn't take them into the fitting room!' It was like dealing with a child." Further incensed at being asked to pay for her purchase, the Mother of the Year reportedly stole a wig off a mannequin's head (which could only be an improvement).

As for those rumors that Little Miss "Oops... I Did It Again" is pregnant by producer J.R. Rotem, they're false, Spears sidekick Sam Lufti tells People. Adds Rotem: "There is absolutely no truth to this." OK! reports that Mama Mia is so mad, she's planning to sue In Touch for printing the story. - Ben Katner
