Are Mila Kunis and Justin Timberlake more than friends with benefits?
Ever since the two filmed their upcoming romantic-comedy of the same name -- about two pals who have sex with no strings attached -- rumors have been swirling that they were heating up off-screen as well.
And they addressed those rumors Sunday night onstage at the MTV Movie Awards -- hands-on.
Kunis, 27, clarified to the crowd that she and Timberlake, 30, were no more than brother and sister.
"Mila and I have never dated," added Timberlake -- who then awkwardly cupped his hands around her breasts to prove there was no off-screen chemistry.
As the crowd uncomfortably laughed, she then grabbed his crotch, looking equally uneasy.
The two then presented the award for Best Male Performance, at which Timberlake cracked, "I think we just found out...what a shameless reference to my penis."
The award went to Robert Pattinson for "Twilight" -- one of many golden popcorn trophies he took home that night.
