Mischa Barton has channelled some seriously strange outfits in recent months - but shocking pink tights teamed with a floral minidress and leopard-print coat really tops the lot. Still, the former OC actress can be forgiven for her sartorial slip-up this time - she was in character, playing a pregnant prostitute. The 23-year-old was caught by photographers mid-way through filming scenes for the American TV series Law and Order: SVU in New York's Meatpacking district. Hollywood heavyweight Sharon Stone has also been roped in for a cameo appearance on the show.Her decision to appear in the TV show appears to be something of a u-turn for Mischa, who had vowed to pursue 'more serious roles'.
