Justin Timberlake sometimes has a hard time keeping his hands to himself.

His latest indiscretion happened Sunday night at the MTV Movie Awards when he and Mila Kunis, co-stars of the upcoming feature Friends with Benefits, were introducing the Best Male Performance category.

Timberlake explained that he and Kunis were the best of friends and as such, he could do things like cup her breasts, which he demonstrated by reaching around her from behind.

Kunis returned the grope by grabbing his crotch.

“We’re like brother and sister,” Kunis said.

The pose lasted a few moments with both grinning. Kunis started to call out “and the winner is” to which Timberlake retorted, “I think we just found out — what a shameless reference to my penis.”

This was not the first time Timberlake groped someone in front of a national audience. He famously tore off Janet Jackson’s top during the 2004 Super Bowl halftime performance. He was later contrite about the act and called it a “wardrobe malfunction.”

Timberlake and Kunis extricated themselves in time to award Robert Pattinson the Best Male Performance trophy for his role in The Twilight Saga: Eclipse.
