Gerard Butler & Brooklyn Decker: Weinstein Pre-Oscar Party!

Gerard Butler suits up to celebrate the Weinstein Company and Chopard during a Pre-Oscars party held at the exclusive Soho House on Saturday (February 25) in West Hollywood.

The 42-year-old actor returned home the day before after successfully completing a treatment program in rehab to address issues with prescription drugs. Earlier in the day, Gerry was seen lunching at Coogies in Malibu.

At the party, Gerard mingled with a few pals including fashion expert Rachel Zalis, who rubbed shoulders with Lady Victoria Hervey, Angelina Jolie‘s manager Geyer Kosinski, and Starz boss Chris Albrecht with wife Montana Coady. (Geyer was Chris‘ best man during his wedding last year.)

Bar Refaeli was seen giving pal Russell Simmons a big hug in the garden area. She introduced Russell to her pal, Israeli actress Noa Tishby, who co-founded the digital pro-Israel activism group Act For Israel.

Across the room, Brooklyn Decker (in Holmes & Yang) and her manager mingled with Chace Crawford and his manager. (This past April, Brooklyn and Chace presented Song of the Year at the Academy of Country Music Awards.) They chatted about Chace visiting Brooklyn on her worldwide promo tour for Batteship since he’s good friends with her co-star Taylor Kitsch.

The Artist‘s Jean Dujardin and Berenice Bejo joined Madonna, Meryl Streep, and Michelle Williams to support Harvey Weinstein, who tapped Tony Bennett to sing “Autumn Leaves” mid-party. A grand piano was brought in for the special occasion!
