Meanwhile, despite announcing their separation in March, the pair, who were married in 2003, have remained good friends and Chris even threw Gwyneth a party two weeks ago to celebrate her 42nd birthday. Chris arranged for the actress’ friends – including Kate Hudson, Nicole Richie, Tobey Maguire and Gavin Rossdale – to join in the boozy birthday bash, which was held in Gwyneth’s backyard. A source said: ”Everyone was seated facing each other so they could talk and tell stories. They were all laughing together… Gwyneth was surrounded by girlfriends and couldn’t stop giggling.”
