Zac Efron dropped by "The Ellen DeGeneres Show" on Wednesday and put the moves on the daytime talk show host. The actor got the studio a little hot and bothered when he acted out "lap dance" and "twerk" in a game of Heads Up with DeGeneres.

Efron was on the talk show to promote "Dirty Grandpa," his new movie with Robert DeNiro. In honor of the raunchy film, the host and actor played the "Bad Behavior" version of the game. The first phrase that Efron had to act out and DeGeneres had to guess was "Lap Dance." Efron wasted no time and got out of his seat, straddled DeGeneres and then gyrated his hips right in front of her face. The actor had more trouble acting out "Tinder" and blushed his way through the clue "making out."

When "twerking" came up on the Heads Up screen, Efron seemed a little hesitant

"Why did you delay on twerking?" DeGeneres asked Efron when he finished acting out the dance move.

"I knew what twerking was, I should have just gone for it," he said to himself as he discussed the game with DeGeneres. "Whenever anyone tells you to twerk, just do it!"
