In Monday’s upcoming episode of Smash, “Callbacks”, we see Katharine McPhee (who plays aspiring actress Karen) continue the arduous audition process as she vies for the lead role of Marilyn Monroe in a musical based on the movie star’s life. In the new number “20th Century Mambo”, McPhee dances, sings and vamps as she transforms from sweet brunette Norma Jean into blonde bombshell Marilyn. Based on the pilot, we definitely thought Karen’s competitor Ivy (played by Megan Hilty) had the part in the bag — now we’re not so sure. Preview Kat’s big number below!
