Alex Pettyfer's character may have looked up to Channing Tatum in Magic Mike, but when cameras stopped rolling, "they had massive fights on set," a source tells the new issue of Us Weekly (out now).
The beefcake to blame, insists another insider, is Pettyfer, 22, who plays a character based on former male revue dancer Tatum. "Alex was a jerk to everyone during filming for no reason. He thinks he's the star of the movie, not Channing or Matthew McConaughey."
To find out how Tatum retaliated, watch this week's Hot Stuff video, as explained by Us Weekly Senior Editor Ian Drew and special guest, singer Bryan Fenkart.
