Bernadette Peters makes her much-anticipated appearance on Monday’s (March 19) episode of “Smash,” entitled “The Workshop,” as Ivy’s (Megan Hilty) mother, Leigh Conroy. For her debut scene, she steals the spotlight away from Ivy at a “Marilyn” rehearsal with a rousing rendition of “Everthing’s Coming Up Roses” in the clip above.

Then watch Ivy dazzle potential “Marilyn” investors, while Karen (Katharine McPhee) fantasizes that it’s her in the lead role. In the final sneak peek clip below, Ivy — fresh off of giving Derek (Jack Davenport) a piece of her mind in last week’s episode — tells her mother off for not supporting her.

Catch the full episode on Monday at 10 p.m. on NBC.
