ET caught up with the 61-year-old actress, who portrayed Jackie Harris on the original '90s sitcom, at the 2017 Tony Awards Meet the Nominees Press Junket in New York City on Wednesday, where she gave us the scoop on the eight-episode reboot.
"Everybody's on board," she exclaimed. "I think contracts have been hammered out and all that -- just gotta sell it!"
According to Deadline, Roseanne Barr (Roseanne Conner), John Goodman (Dan Conner) and Sara Gilbert (Darlene Conner) are all reprising their roles, and ABC and Netflix are reportedly both bidding on the project.
"I don't think it's been sold, but if anybody buys it, we'll all be there," Metcalf added. "I can't imagine where the writers would take it -- it could be open to anything. I can only imagine there'll be a lot of laughs among the cast because that's how it used to be."
And speaking of laughs, Metcalf's daughter, Zoe Perry, was recently cast to play the young version of Sheldon's mother, Mary Cooper, in The Big Bang Theory spinoff, Young Sheldon. Metcalf plays Mary in CBS' original comedic series, so it's a natural, perfect fit!
"She [Zoe] got that great Big Bang spinoff job, which is so wonderful," Metcalf gushed. "I just love that the little boy [Iain Armitage]. The cast is absolutely adorable and it's set in the '90s because it's Sheldon at age eight, I guess."
"And then it brings in all the things he's talked about on Big Bang, which is that he has a twin sister and an older brother and a dad, and then she, my daughter, [is] his mom," she added. "So either I'm playing her, or she's playing me! I can't figure it out."
No word yet if Johnny Galecki will reprise his role as David Healy on the Roseanne revival, but after hanging out with Metcalf on the The Big Bang Theory set, we have a feeling it won't be too hard to talk him into it.
As we patiently wait to hear more on the reboot, watch the video below to hear Barr's reaction to the news.
