Mischa Barton partied with her model pal Irina Lazareanu Tuesday night in Paris to celebrate Dita Von Teese's 38th birthday. The actress is in France after a seriously PDA-filled trip to Milan with her music-loving boyfriend DJ Ali Love. Mischa's enjoyed an extended hiatus from work to focus on fashion and traveling, but some of her former O.C. buddies are reuniting for a new project. Rachel Bilson will team up with the series creator, Josh Schwartz, on his next show, a primetime comedy called Ghost Angeles.
