Olivia Munn instituted "voyeur watching" on set while filming male stripper movie Magic Mike.

The 31-year-old actress is preparing for the release of the movie which stars hunky half-naked castmates Joe Manganiello, Matthew McConaughey and Matt Bomer.

Olivia was so compelled by her handsome ensemble's dancing, that she found herself on set at unwarranted times.

"I think on set, with all these guys, I'm not a sexy tomboy; I'm not a tomboy; I'm not anything. I'm just a voyeur, watching them," Olivia joked to MTV News.

"I'm on set when I'm not even working for, like, four hours, but I heard they're dancing and they're going to be naked, so I'm gonna be here early watching. So that's what I am on set: more the voyeur watching."

Out of all of the men, Olivia thinks Channing had the smoothest dance moves.

"He's truly, truly talented, and he's so fun to watch, and it's so sexy as well," she gushed. "And then the person I was really impressed with was Matt Bomer, 'cause I didn't know he could dance. He's got this juicy butt. Like, I just want to make wishes on it, it's so beautiful."

Magic Mike is set to be released in US theatres this June.
