“Big Bang Theory” star Johnny Galecki has returned to the series where he found fame, joining his old “Roseanne” family to film the show’s reboot.
Series star Roseanne Barr shared the news on Twitter on Tuesday. ET has learned that Galecki is on set rehearsing this week and will film his episode on Friday.
“We have got our Johnny Galecki back on ‘Roseanne’ this episode – what a joy to work with such a deeply empathetic actor,” Barr wrote. “Very moving 4 all of us. #JOY.”
News of Galecki’s (who played David Healy) return comes after Sara Gilbert, who portrayed his onscreen wife, Darlene, told ET in September that he was poised to return.
“We’re in very productive, amazing talks and we’re hopeful that it will work out,” Gilbert shared.
Cast members including Gilbert, Barr and Lecy Goranson then started sharing pics from set on social media last month.
Barr couldn’t be more thrilled to have her TV family back together, sharing how the reboot is a “dream come true” in another tweet posted on Tuesday.
“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.
The 65-year-old actress also gushed about the new young actors coming in to play her grandchildren, including Darlene and David’s teenage daughter, Harris, and 9-year-old son, Mark.
“The kids playing my grandchildren on the ‘Roseanne’ show are fantastic actors and I am in love with all three of them,” she tweeted. “They r all movie stars!”
The series will air on ABC in 2018. See more on Galecki’s return in the video below.
