Zac Efron Steps Out In Public!

[Zac Efron just got back into town from filming The Death and Life of Charlie St. Cloud in Vancouver and has wasted no time hitting up the party scene. Last Wednesday, he swung by Nylon's party at XIV solo, where his High School Musical costar Ashley Tisdale was also hanging. (The two had just lunched together on the Monday prior.) And on Friday night, Zac was all over the place--first heading downtown to check out the opening of Hyde Lounge at the Staples Center arena.

The HSM hunk hung courtside at the Lakers game for a bit before swinging by the lounge, where he held court with three guy friends. "The boys were really enjoying the game and not noticing the gaggle of girls trying to get his attention," a source tells E! News.

But it was another story back at a West Hollywood nightclub... Zac and his buddies moved the party to MI6 after the Lakers game. "He showed up pretty late, around midnight," another source tells E! News. "He seemed like he was in a good mood--dancing, talking to a bunch of people--and he was definitely flirting with some girls."

What does this all mean for his relationship with Vanessa Hudgens? Although the couple hasn't been photographed together since October at a Vancouver Giants hockey game, a source close to the twosome says they're still on. So maybe she's just busy filming her own movie, Sucker Punch, in Canada?

Vanessa's rep didn't respond to our request for comment. Still, it needs to be said: We love seeing Zac on the nightlife scene, but watch out, V: He's a hot commodity, and Tinseltown chicks can be ruthless. As long as your schedule permits, we suggest joining your guy next time!]

Ah, yes! The ruthless chicks competing for his affection. The nightlife. The manly viewing of the sports games. The roller coaster relationships! Wow, Zac really has it all - including a Tom Cruise complex.
