A few weeks ago, Efron and his "High School Musical" costar Corbin Bleu went to the Flashdancers Gentlemen's Club in New York City. Sources claimed the group stayed for four hours getting bottle service and lap dances. "They were nice kids. They seemed to have fun," a source told People.
"I had this image of what it would be like. I've heard a lot about these places, mostly from rap music. So I envisioned myself on a nice couch, stunna shades, with like T-Pain and Usher, you know, making it rain money," Efron said on Jimmy Kimmel Live. "And it just wasn't like that."
Although reports claimed the group spent $2,000 on dancers, the star says, "No, no, not at all ... I don't remember. I don't think I opened my wallet."
