Katy Perry lends her star power in a new promo for the upcoming episode of "Saturday Night Live". Appearing with this week's host Bruce Willis, the pop star who will serve as musical guest gives the actor some hosting tip.
"My hosting tip number one is show some skin," so the girlfriend of rocker John Mayer says as she pulls her jacket open and reveals a leather bra. Willis then points to his bald head to show that he has already shown some skin. "Oh, yeah you're good then," she comments.
The action movie vet will host the variety series for the second time on October 12 after tackling the same duty in 1989.
"SNL" airs Saturdays at 11:30/10:30c on NBC.
