Like any good mother, Demi Moore gave her daughter Rumer a pole-dancing lesson while partying at the Chateau Marmont, along with Ashton Kutcher, Jennifer Aniston, and Leonardo DiCaprio. As Moore flung herself around a pole upside down, "Leo gave Ashton a high-five." According to "someone who was there," Gerard Butler and Madonna were "grinding" at Guy Oseary's Oscar bash and then Moore jumped in on the steamy dance action. Jennifer Aniston, meanwhile, poses with Butler for the April cover of W, in a photo spread oddly reminiscent of Brangelina's 2005 "domestic bliss" cover shot. Justin Timberlake is reuniting with his ex Cameron Diaz as her love interest in the upcoming flick Bad Teacher. We're sure Jessica Biel is thrilled about the situation. Turns out Christian Bale hasn't spoken to his mother in two years (ever since they got into a screaming fight the night before his Dark Knight premiere, she called the cops, and he kicked her out). Now she's trying her luck at winning him back by chatting with the press. And Taylor Momsen has no intention of being a role model to her tween fan base, commenting, "If parents don't like some of the stuff I do, then they shouldn't let their kids watch me I smoke, so what? It's not like I'm sitting there going, 'Kids, you should go buy a pack of cigarettes.'"
According to Britain's ever-reliable Sun, Nicolas Sarkozy and Carla Bruni are both having affairs, he with France's 40-year-old ecology minister and she with a musician (isn't it always a musician?). Jeremy Renner says he never hit on Jessica Simpson, he's "not a ladies' man," and the pair was merely chatting because Simpson's hairstylist (her date) also did his mother's hair (his date). Snooki and her personal-trainer boyfriend (whom she fell for on Facebook) are still going strong. They even had a romantic getaway at a bodybuilding show in Ohio. And Ethan Hawke, his dog, and Sam Mendes lunched outside at the Maritime.
In tragic news, eighties teen idol Corey Haim died at 3:30 a.m. of a drug overdose. Kate Gosselin, meanwhile, parted with her $7,000 hair extensions. Def Jam CEO Antonio "L.A." Reid backed out of giving a speech at the Billboard 2010 Music & Money Symposium at the last minute, telling delegates his son suffered a head injury, when he was really just nervous about discussing his shaky future with the record label. In poor fashion-house form, Givenchy canceled on five of its models the night before their show, leaving the undoubtedly thin and frail girls to fend for themselves and cover their own travel costs. Oprah announced that she sees a bit of herself in Gabourey Sidibe and referred to her as "a true American Cinderella." And the Film Academy claims they "snubbed" Farrah Fawcett because she was better known for her "remarkable television work" and would be more appropriately honored at the Emmys. Like Michael Jackson was known for his great film talent? Bea Arthur was also omitted from the montage, but, sadly, no one seems too torn up about that.
