Tron: Legacy actress, Olivia Wilde, graces the cover April’s Cosmopolitan magazine in a sexy pink Michael Kors jersey top and skirt.

In the interview inside, Wilde retells her most embarrassing moment which happens to involve our Commander in Chief, Barack Obama.

Wilde says: “[Obama] 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.”

OMG! That is hilarious. I can totally see myself doing the same thing – well, except, there really isn’t any reason for the Chief to be calling me anytime soon…Sigh…
