Katharine McPhee is such a Smash that she is one of the lucky twelve to make our “Sexy Dozen” list (which also includes Ewan McGregor) for InStyle‘s new June issue. And we’ve just released footage of the steamy shoot! Go behind-the-scenes of the Smash star’s boxing ring-side photos, and see the actress knock out some seriously sultry poses (Marilyn would be proud). “To me, Marilyn Monroe was sexiest when she wasn’t aware of it—it just came from within,” said McPhee, who portrays the blonde bombshell on the NBC hit show. Watch the exclusive video above, and see who else made our Sexy Dozen list in the June issue, on newsstands Friday.
