A High School Musical Star Walks Into A Bar...

It's not like he's actually IN high school, but you can imagine how stunned we were to see the squeaky clean Disney prince at MI-6 in West Hollywood last night! Zac Efron went to the hotspot with a few male pals, which is really making us wonder ... where the heck is Vanessa? Is she cool with him spending so much time without her, or are these two broken up? We haven't seen the kissing co-stars together in ages, so we think it's either it's time for a Zanessa photo op or time for Zac to debut a new lady love! This looks like a bachelors' night out to us!
