Ivy (Megan Hilty) seems to finally be waking up to the fact that her relationship with Derek (Jack Davenport) is going nowhere on Monday’s (April 30) episode of “Smash,” when it looks like he’s planning to hook up with yet another of his leading ladies — “Bombshell” star Rebecca Duvall (Uma Thurman).

In the sneak peek clip above, Ivy channels her frustration and some Mary J. Blige-style gumption into belting out a cover of Rose Royce’s “I’m Goin’ Down.”

Also in this episode, Rebecca gives Derek a little birthday surprise, singing a heavy-lidded version of “Happy Birthday” as Marilyn Monroe. Check out the video below.

“Smash” airs Monday at 10 p.m. on NBC.
