The Playboy Club has cast its first guest singer: Colbie Caillat will brighten up the upcoming NBC drama playing famed vocalist Lesley Gore.

The Playboy Club is enlisting a series of stars to portray famous performers from the 1960s in the period drama, and Caillat is the first person cast. She will perform Gore’s classic song “It’s My Party” on the show.

But you can catch Caillat sooner than that on NBC’s America’s Got Talent, where she’s going to perform her single “Brighter Than the Sun” tomorrow night. In the meantime, check out The Playboy Club‘s bunny-stuffed psychedelic poster. The drama premieres Monday, Sept. 19 at 10 p.m.
