The costars addressed rumors they were hooking up off-camera at the MTV Movie Awards Sunday with a little friendly P.D.A. – and nothing was hands-off.
So are they boyfriend and girlfriend? More like brother and sister, Kunis, 27, says.
"Even though we're in the movie Friends With Benefits, Mila and I have never dated," Timberlake, 30, clarified, before the two presenters playfully showed how comfortable they were together – by jokingly groping each other.
Friends With Benefits arrives in theaters July 22.
