'Smash': Katharine McPhee As Marilyn Monroe In '20th Century Fox Mambo' (VIDEO)

It's the audition of a lifetime for Karen Cartwright on NBC's "Smash." The young aspiring Broadway performer, played by Katharine McPhee, is up for the role of Marilyn Monroe and she's bringing her A-game.

Karen is up against a Broadway veteran, Ivy Lynn, played by Megan Hilty. Viewers have already started picking sides, something Hilty said makes for great TV. "I've already gotten t-shirts sent to me," Hilty told HuffPost TV. "I plan on rocking my Team Karen t-shirt full force. Every show needs a good rivalry, right?"

In this preview from the second episode, "The Callback," (airing Mon., Feb. 13) watch McPhee's Karen turn into Marilyn Monroe before your eyes as she performs the original song "20th Century Fox Mambo."

"Smash" airs Mondays at 10 p.m. EST on NBC.
