Producer Joel Silver was the host to many celebrity guests at his Memorial Day bash yesterday in Malibu. Joel throws a special holiday bash every year, and his 2012 event was as star-studded as usual. Gavin Rossdale, home during a break from his tour with Bush, dropped by along with his wife, Gwen Stefani, and their boys, Zuma and Kingston. The family played together on a bouncy castle Joel rented for the occasion, then checked out the beach.
The little ones were able to say hi to Tobey Maguire's kids while the adults caught up. Both Courteney Cox and David Arquette swung by as well with their daughter, Coco, and Kate Beckinsale brought her daughter, Lily Sheen, and husband, Len Wiseman. Robert Downey, Jr. and his wife, Susan, said hello to their friends, but left newborn son, Exton, at home. Josh Hartnett and Ashley Greene, though, dropped by solo, as did Selena Gomez after her boyfriend, Justin Bieber, took off for Europe.
