(PEOPLE.com) — Looks like Justin Timberlake and Mila Kunis are taking their roles in upcoming romantic comedy “Friends With Benefits” to heart.
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.
