Katharine McPhee looks very sexy in her GQ Magazine photo shoot.

The timing for the pictorial is good, the American Idol season five runner-up Katharine McPhee is in NBC’s highly anticipated show Smash, which is receiving rave reviews.

In her interview with the magazine, she gives three reasons why straight men should watch the show.

Reason #1: Your lady does it for you. Now do it for her. "Listen," McPhee says, "I go see all the guy movies, so now I know I love them. But you have to be open to it. I would say to the girlfriends out there: Just nail him down, make him watch an episode with you."

Reason #2: It's not like they're singing constantly. "I can understand why guys wouldn't be into Glee. You know, that's a pretty heavy musical show. That show does, like, six songs in an episode. We'll do, at most, three."

Reason #3: "Okay, how about this: What if I tell your readers that in episode five I take off all my clothes?" Sold! But hold on—would it be true? "I mean…no." McPhee laughs mischievously. "But can't we just say that?"
