‘Roseanne’ revival finally confirms Johnny Galecki’s return

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.

Yes, "Big Bang Theory" star Johnny Galecki has joined his former co-stars for the "Roseanne" reboot.

Roseanne Barr shared the news of Galecki's return on Twitter.

"We have got our Johnny Galecki back on 'Roseanne' this episode – what a joy to work with such a deeply empathetic actor," Barr tweeted of the actor's return. "Very moving 4 all of us. #JOY."

Barr wrote in a subsequent tweet how special the reboot is to her.

"This 10th season of 'Roseanne' is just a dream come true for an old lady comic who fought so hard 2 honor working class ppl in America," Barr wrote.

Cast members including Sara Gilbert (who portrayed Galecki's onscreen wife, Darlene), Barr and Lecy Goranson all started sharing pics from set on social media last month, but Galecki (who played David Healy) was nowhere to be seen.

The "Roseanne" revival is set to air on ABC in 2018.
