Vanessa Hudgens is beginning to have doubts about BF Zac Efron’s heterosexuality. (Shocker!) Vanessa is becoming unattracted to Zac’s compulsive makeup wearing and obsessive meltdowns over his weight and complexion.

A source tells Star Magazine:

“She wants to date a man, not a little girl.” “Zac can be incredibly vain, obsessing about his weight.”

Baby V was left particularly red-faced just before the 12th birthday party for her kid sister, Stella, on November 13th. Zac had a meltdown and refused to attend the affair after noticing a pimple on the side of his face.

“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.”

Vanessa was only able to calm Zac down after she gave him her concealer to cover up the blemish.

“Vanessa told him to stop being a sissy and freaking out when he gets blemishes. Sometimes, when he goes out, Zac even wears makeup to cover up his imperfections.”

“Vanessa doesn’t want to share makeup with her boyfriend. It makes her feel weird.”
