Rosie O'Donnell is heading to Mom, and we'll definitely be tuning in. According to People Magazine, Rosie will be guest-starring on the CBS sitcom as Jeanine, the ex-girlfriend of Allison Janney's character Bonnie from "back when she was drinking and drugging." Allison has won two consecutive Emmys for "Outstanding Supporting Actress in a Comedy Series" for playing Bonnie, and with this reveal, she'll also be the first major LGBT character on the show.

Recently, Rosie's been really making the rounds as a guest star. She's been prominently featured in many episodes of ABC Family's The Fosters, and we also recently reported that she'll be guest-starring on Empire soon as well. Rosie's episodes of Mom aren't slated to run until early 2016, which gives you plenty of time to catch up on the show before Rosie's appearance. With this track record, we can't wait to find out where Rosie will show up next!
