There's no fooling Ellen DeGeneres! Vince Vaughn made an appearance on Tuesday's episode of The Ellen DeGeneres Show, when he walked out sporting a thick head of long brown locks.

Of course, the hair wasn't real, but rather a poorly placed wig covering Vaughn's semi-bald head. Once DeGeneres ran her fingers through it, he was forced to come clean.

"I shaved my head for a movie, completely clean," the 46-year-old actor said. "And now, thankfully – because you don't know at my age – it's growing back."

When asked what he plans to do with the stubble, Vaughn coyly replied, "It's unclear what will happen."

He did note that his 5-year-old daughter, Lochlyn, has been enjoying giving her dad a hard time.

"My daughter likes to humiliate me with it," he said. "I take her to her kindergarten at which point she will pull off my baseball cap and say, 'Ha ha ha, look who doesn't have any hair.'"
