Zac Efron A One Woman Guy

Vanessa Hudgens can sleep soundly at night when her boyfriend Zac Efron is away on location - he's vowed never to play the field with a string of girls.
 
The High School Musical hunk has a legion of female fans but he's adamant he never takes advantage of the opportunities his fame brings.
 
And although he's sometimes confused that he doesn't sleep around, he's happy he has a steady relationship with former co-star Hudgens instead of bedding different women every night.
 
Efron tells Details magazine, "I think a lot of guys would enjoy that, but I'm not really like that...

"Believe me, I rack my brain thinking, 'Why am I not out there playing the field?'... But it's not in my heart."
