During a taped classroom skit for The Ellen DeGeneres Show, which airs on Friday (18Nov16), the Wedding Crashers star asked kids to name their favourite celebrities and when one student, who called the actor Prince Vaughn, revealed he was a fan of Downey, Jr., Vince insisted the movie star was a meanie.

"I've actually met Robert and, honestly, (he's) not the nicest of guys," he quipped. "If you like people to tip then he may not be for you."
