In news that may make gen-Yers' heads explode, Jackee Harry is joining the cast of "Girl Meets World."
The sassy comedian -- who played Tia and Tamara Mowry's mother on the '90s sitcom "Sister, Sister"-- will appear in the Disney Channel pilot, the network confirmed to Access Hollywood on Thursday.
Jackee (who won an Emmy for her work on "227") joins the growing roster of former "Boy Meets World" stars set to appear in the highly anticipated spinoff, including Danielle Fishel (Topanga Lawrence) and Ben Savage (Cory Matthews).
William Daniels, who played lovable teacher Mr. Feeny on the '90s show, will also reprise his role in "GMW."
Newcomers Riley Matthews and Teo Halm will play now-married couple Topanga and Cory's children.
If the show is picked up, it could land on Disney Channel's 2013-14 schedule.
