Carly Rae Jepsen is heading back to SNL… again… sort of. The “Call Me Maybe” singer is slated to appear as herself on the Saturday Night Live-themed episode of Castle, “Dead From New York,” EW has learned exclusively.

Here’s the situation: When Sid Ross, the powerful creator of a long-running sketch comedy show, is killed, Castle and Beckett are called to investigate. But as they delve into the victim’s life and the colorful world of Saturday Night Tonight, they uncover a shocking secret that may explain Sid’s murder.

Fresh off her real-life appearance on Saturday Night Live, Jepsen will appear as a musical guest on Castle‘s late-night comedy sketch show. And yes, she will be singing her new hit song “I Really Like You” in addition to having some lines.

The episode, which also features Jaleel White as the star of Saturday Night Tonight, will be the 22nd of the season. Castle returns Monday, April 20 with episode 20.
