efronstrippers.jpg Zac Efron and two buddies spent more than $2,000 on lap dancers and vodka at Flashdancers Gentlemen's Club in NYC on Sunday night, and get this -- the boys stayed until 3am, just hours before the premiere of his new film, Charlie St. Cloud!

Efron was joined by his High School Musical co-star Corbin Bleu and another unidentified pal, and a spy told the NY Post:

    "Zac came in Sunday night around midnight with Corbin and one other male friend, who paid for everything. They were seated in the VIP lounge behind the main stage. There was only a rail between them and the girls who were dancing. They ordered one bottle of Belvedere vodka and were enthralled with the dancers. They were interacting a lot with the girls and reaching out and showering money on them. There were three girls who Zac and his friends particularly liked and they asked to do personal dances at their table. The girls were all slim pretty brunettes, a bit like Zac's girlfriend, Vanessa Hudgens. They were two Americans, called Shannon and Brandi, and a gorgeous Brazilian called Raquel."

A rep for Flashdancers confirmed that Zac and his pals were there, but wouldn't comment further. Hey, as long as Zac gets to his premiere on time and looks sexy, there's nothing wrong with a little celebration! And while Vanessa Hudgens may not like it, Zac certainly wouldn't be the first guy in a committed relationship to visit a booby bar!
