According to Entertainment Weekly, Bell will appear on the series as a potential love interest for Brian Griffin, the anthropomorphized family dog who's become known for his canine-human relationships throughout the years. Bell will reportedly voice Martha, a co-worker of Brian's at a suicide prevention hotline who has her own theme song.
Meanwhile, Louis C.K. will appear as himself in the season premiere, which parodies the Emmys and which will also feature Modern Family's Ty Burrell, Julie Bowen, and Sofia Vergara along with Real Time's Bill Maher. In the episode, patriarch Peter Griffin, who's creating his own family series in search of some Television Academy acclaim, will prod Louis C.K. and the other guest stars for advice on how to score an Emmy nod.
Family Guy Season 15 premieres Sunday, Oct. 1 at 8:30/7:30c on Fox.
