Justin Timberlake Locks Lips With Olivia Wilde (PHOTOS)

Calm down, celebrity scandal junkies; this isn’t what it looks like.

Yes, Justin Timberlake—who lately has been plagued by rumors that he’s been cheating on his girlfriend, Jessica Biel—was spotted on the streets of Los Angeles on Friday, planting one on House hottie Olivia Wilde. But there’s a perfectly innocent explanation: The pair were merely filming a scene for their upcoming sci-fi thriller, I’m.Mortal, which required the singer/actor to perform mouth-to-mouth resuscitation on Wilde.

So go ahead and enjoy our photo gallery of the pair guilt-free. And make sure to drop by Celebuzz’s Actors on Set gallery to see more famous folks putting in a hard days’ work.
