Stepping out for an evening of discussion and fun, Olivia Wilde attended the Kelly Oxford Lies to Olivia Wilde event on Monday (April 1) in New York.

Donning a plated black mini skirt and a black turtleneck sweater, the “Incredible Burt Wonderstone” beauty posed alongside her friend and author Kelly Oxford before the panel began.

As the 29-year-old readied for the big night, she humorously tweeted, “I'm prepping for my q&a with @kellyoxford. Mostly I want to know how she popped out 3 kids and didn't get deformed.”

Also on hand at the Housing Works Bookstore was Wilde’s main man, fiancée Jason Sudeikis, who mingled among the assembled crowd before the “Everything is Perfect When You’re a Liar” book discussion got under way.
