Vanessa Hudgens Plays Prank on Zac Efron

Vanessa Hudgens recently played a prank on Zac Efron, reports Life & Style. Vanessa was egged on by her friends to see how loyal Zach was. So she sent in a hot girlfriend of hers to talk to him at the gym where he works out.
“He had no idea she was a friend of Vanessa’s,” says an insider involved in the scheme. “The hottie started talking to him, but Zac didn’t flirt back — and she’s gorgeous!”
Apparently Zac passed the loyalty test! Vanessa friends say he's only got eyes for her.
