Zac Efron and Vanessa Hudgens might be on the rocks.   Zac and Vanessa are both very young, but seemed to be handling a relationship and stardom very well for teenagers.  But it seems the flame of romance may be dwindling for the couple, at least according to some reports.

More pictures of Zac and Vanessa after the jump…

Why the rumors for the rift between Zac and Vanessa?  Well, it seems the hot and heavy twosome are spending more time apart.  Sure, he’s been traveling the world and promoting his new movie, but there’s more.  Like another woman he may be interested in more.  From Star Magazine:

The teen heartthrob hit his movie’s March 26 London premiere solo, but he wasn’t planning to spend the whole night alone.

Zac, 21, extended a special premiere invite to Bonnie Wright, 18, a sassy redhead who stars as Ginny Weasley in the Harry Potter films.

Hours after the two walked the red carpet separately, they met up for a midnight rendezvous on the back streets of London and ended up at a low-key bar for a long, quiet date!

OOoooh.  Zac might be looking for love elsewhere?  I’m not convinced, but since there’s a bit of smoke here, he rumor may be on to something.  Keep a watch out…I’m betting Zac and Vanessa are over by summer.
