Olivia Wilde looks perfectly put together in a sexy pink Michael Kors jersey top and skirt on the cover of April's Cosmopolitan magazine, but she admits inside the mag that she once made a fool of herself in front of America's commander in chief.

"He was calling to thank me for traveling to Iowa in October 2007 to volunteer for the campaign. I was very professional the whole time we spoke, then I hung up the phone -- or so I thought -- and started squealing for about 15 seconds," Wilde admits.

"I later found out from a friend who was with him that he listened to the shrieking and laughed the entire time," she says.

The newly single 'Tron: Legacy' actress (she recently separated from her husband of eight years, Italian prince Tao Ruspoli) has been linked to heartthrob Ryan Gosling, but she tells the mag she is focusing more on her professional life then her personal life these days. She is hoping to branch out into uncharted territory with the next role she takes on.
