Justin Timberlake and Mila Kunis were bringing sexy back at the MTV Movie Awards Sunday.
The hot twosome took to the stage to present the first award of the night (Best Male Performance - Robert Pattinson) and took the chance to clear up some rumors as well as embark in a gropefest!
Denying that they are dating and explaining that they are basically just like brother and sister, Timberlake and Kunis proceeded to act in a decidedly un-sibling like manner.
Timberlake went in for the kill with a straightforward front facing boob grab while Kunis managed to slip in a backward groin grope.
Not for the faint hearted!
