The Second Annual Pink Party

Michelle Trachtenberg, in 14 Carat earrings and a blouse by Generra, chatted with Ginnifer Goodwin, who wore a Catherine Malandrino blouse, Tsubi jeans and a vintage blazer. Goodwin noted that her own mother is a cancer survivor.

"This T-shirt I had made," said Wilmer Valderrama. "It has the Cadillac sign, and I have an Escalade, so you know I love it."

Maria Menounos is soon to appear in the film Kickin It Old Skool.

"One of my good friends organizes this every year, so I think it is fantastic," said Marcia Cross. "I have no pink on-I'm just lucky I can get dressed right now!"

Zooey Deschanel, wearing vintage and a Kate Spade bow, attended with sister Emily, who came in Dolce & Gabbana. "The music is amazing," said Zooey. "I was going to hit the dance floor as soon as I'm done talking to all the people that I know."

Lara Flynn Boyle and Kim Raver grabbed a spot on one of the couches next to Michael Michele, who was taking a cupcake break.

"I'm in the true life story of Geralyn Lucas, Why I Wore Lipstick to My Mastectomy, that's coming out next month on Lifetime," said Sarah Chalke, in Marc Jacobs. "It was such an honor to meet her and to play her."

Amber Valletta and Nicole Richie, who wore Pucci. "It's the only pink thing I own," Richie said. "I don't like pink. I mean, I love it for the party. It's great, but not on me."

"I love pink," said Melina Kanakaredes, wearing a blouse designed by her friend Claudette, who is starting her own clothing line. "I have two little girls-I'd better love pink!"

"It's such a fun environment, a good sort of energy and light," said Lake Bell. "It's nice to go to an event that doesn't seem sort of gray and dark. The scantily clad dancers were sort of a really fun touch."

Dennis Quaid came with his wife, Kimberly Buffington.

A dancer heated up the pool-top dance floor as DJ AM spun a playlist that featured plenty of '80s tunes.

The gift bags contained Giada De Laurentiis cookies, which Maria Bello took home for her son.
