Mom: Rosie O'Donnell returning to the CBS comedy

Just call her Rosie the Returner.

Former talk show host Rosie O’Donnell will reprise her role as Jeanine, the ex-girlfriend of Bonnie (Allison Janney) in an episode of Mom this season, EW has learned exclusively.

In the yet-to-be-scheduled episode, Jeanine upsets Bonnie when she suggests Christy (Anna Faris) abandon her dream of becoming a lawyer to take a job in her real estate office.

O’Donnell first appeared on the CBS sitcom last February. She was introduced as a woman who hooked up with Bonnie when she was “drinking and drugging,” the network said.

“I had the best time on set,” O’Donnell told PEOPLE at the time. “Allison is the best kisser!”

Mom returns for a fourth season Oct. 27 on CBS.
