Does Katharine go nude for 'Smash'?
In the past couple of months, it seems as if everyone and their mother has been dressing up like Marilyn Monroe. Well, now it’s Katharine McPhee and Megan Hilty’s turn.

Last night, Katharine and Megan showed off their talents in the premiere of NBC’s hotly anticipated new musical drama Smash, about two rival actresses vying for the role of the blonde bombshell in an upcoming Broadway musical.

They now join a growing list of stars who have portrayed Marilyn in one way or another, including Michelle Williams, who just picked up an Oscar nomination for the film My Week With Marilyn.
