Lindsay Lohan and Avril Lavigne are in a feud because Lohan supposedly snubbed Lavigne at an event, then the two got in a screaming fight at the Chateau Marmont. But LiLo fled Hollywood to spend Mother's Day with Dina at Abe & Arthur's. She also released a new single called "I Wanna Be Bad," and it's pretty bad. True to form, Lady Gaga went out in Sweden wearing see-through panties. Britney Spears ate lunch at a gay bar. A preggers Claudia Schiffer posed nude for German Vogue. Katy Perry tops Maxim's Hot 100 List, Angelina Jolie sank to No. 38, and Jennifer Aniston's not even on it. Perry (who's engaged to Russell Brand) also says she wants a "small wedding" but a "fat reception."

Donald Trump is staunchly defending some scantily clad Miss USA contestants. The Trump Soho banned babies from its restaurant and wouldn't let supermodel Karolina Kurkova in with her 6-month-old. Jill Zarin is sorry that she mistook Bethenny Frankel's new daughter for a son. Zarin also hopped from booth to booth at the Limelight Marketplace hunting for free swag. Alexa Ray Joel announced that her supermodel mother, Christie Brinkley, "wishes she looked like [her]." Tiger and Elin will share joint custody of their children. And Kate Gosselin threw a pool party for her sextuplets in 47-degree weather.

Ed Westwick escaped Hollywood's Roosevelt Hotel when a crew of techies swarmed the place with their cell phones, flip cams, and iPhones waiting for "tech hottie" Olivia Munn. David Lee and his girlfriend dined a few tables away from Quentin Tarantino at Quattro. There's a Facebook campaign to get Betty White to host the Emmys, and Dancing With the Stars is also vying for the Golden Girl. And Cynthia Nixon says she loves her girlfriend because she's "like a short man with boobs … A lot of what I love about her is her butchness."
