Vanessa Hudgens is reportedly sick of Zac Efron’s girly ways and is trying to persuade him to be more manly.

The final straw, according to Star magazine, was when Zac refused to attend Vanessa’s little sister’s birthday party – because he had a zit.

An insider tells the U.S. mag: “He just flipped out. He knew there were a bunch of girls at the party who worship him — and he didn’t want them all staring at his pimple.”

Apparently Vanessa is fed up with being the more masculine half of the partnership.

 A source said: “She wants to date a man, not a little girl. Vanessa told (Zac) to stop being such a sissy and freaking out when he gets blemishes.” 

Sounds like she’s got her work cut out.
