The Roseanne revival has finally confirmed that it’s adding another old cast member to its lineup and we’ll give you three guesses who it is, though you’ll probably only need one at this point. Big Bang Theory star Johnny Galecki has joined his former co-stars for the Roseanne reboot. Galecki will be returning for one episode.
Roseanne Barr shared the news of Galecki’s return on Twitter.
