Zac Efron Admits to Taking Viagra? "I Can't Confirm or Deny That," Actor Says

Star of That Awkward Moment recalls "a friend of a friend" trying the drug

Did Zac Efron get all Method for his latest role?

Well, the guy certainly seemed to hint at that during an appearance on Monday's Conan with his That Awkward Moment costar Miles Teller.

While discussing the movie's most memorable scene, in which Efron and Teller's characters take Viagra and wind up planking over a toilet in an effort to pee with erections, host Conan O'Brien can't help but ask Efron if he had ever actually taken the drug.

"I can't confirm or deny that," the 26-year-old actor said with a straight face, before noting, "I had a friend of a friend try it, like a half of a half of a half of a Viagra."

To which O'Brien quickly gave an oh-come-on kind of look and said, "This is you."

Nevertheless, Efron continued, "My friend told me that it turned him into, like a horse, and then everyone just gets tired, and then you just don't know what to do."

Yep. Nothing like having a "friend" give you that kind of a, um, heads up!
