Although Justin has only officially hosted the show twice, he says the producers are great about letting him drop in for some "drive-by comedy" whenever he's in town—which is how Justin's "Single Ladies" performance came about.
It all started with a call to friend and SNL performer Andy Samberg—who asked if he'd seen the video yet. "I actually hadn't," Justin says. "So he sent a copy of the video to me, and I called him immediately and I said, 'We're going to be dancers in the video, aren't we?'"
Justin says he doesn't take himself too seriously. "You put a grown, you know, pretty hairy man in a leotard, and it's just funny," he says. "I felt sexy in the pantyhose. I'm not afraid to say that."
