Olivia Wilde  stepped out last night in LA for the Nylon August issue launch party  on the Mondrian hotel's pool deck. Olivia is home in the City of Angels after joining her costars Daniel Craig  and Harrison Ford  at the Comic-Con premiere of Cowboys & Aliens in San Diego last week. The actress debuted new bangs as she played host for the bash, which also brought out Paris and Nicky Hilton . Olivia is the magazine's current cover girl and opens up about her recent divorce in the accompanying interview. The newly single Olivia told Nylon she self-medicated with food  after her split, joking that it was a better choice than crack cocaine, and also admitted that she's still trying to figure out the dating scene.
