Praise be. Mischa Barton has gone back to work. Because swanning off to Paris for the shows and propping up the bars in Camden gets so boring after a while, doncha know. The former OC star was on set in London's Regent's Park yesterday filming for Ashton Kutcher's new show, The Beautiful Life, based on a group of models. Mischa plays Sonja, ‘a supermodel and veteran of the high-fashion circuit who is struggling to keep on top and is in danger of slipping'. She's promised to be uber-bitchy, too. And judging by the three outfit changes in less than three hours – including everything from a Chanel jacket to those Stephen Sprouse for Louis Vuitton leggings – her character will be as fashiontastic as you'd expect from a show that will be aired on the Gossip Girl channel (otherwise known as The CW). Do we spy a new fashion-meets-TV obsession?
