Was it method acting, or just penis envy? Either way, Lady Gaga sure knows how to commit to a look. And the pop icon, who came to the VMAs as her male alter ego, Jo Calderone, didn't stop at a five o'clock shadow to sell it. She wore a prosthetic penis, an insider confirms to Us Weekly. "I am just a guy," Gaga, as Jo, told the press backstage at the VMAs, before reportedly heading to the men's room to take a leak.

The gender-bending outfit and attitude drew both praise and ire from critics. But when Lil Wayne's pants are tighter than Lady Gaga's, you know that's rock 'n roll.
