Here’s Who Will Play Kaley Cuoco’s Mom on ‘Big Bang Theory’

Fans of The Big Bang Theory will finally meet Penny’s folks!

Kaley Cuoco’s onscreen mother will be played by none other that Sons of Anarchy alum Katey Sagal, according to executive producer Steve Molaro. Meanwhile, 30 Rock actor Jack McBrayer will take on the role of Penny’s sibling.

“We are finally going to meet more of Penny’s family,” Molaro told the crowd during a San Diego Comic-Con panel for the CBS comedy. “We’re going to be meeting Penny’s mom and her brother in the first episode back. We’re super excited that Katey Sagal will be playing Penny’s mom.”

However, this won’t be the first time Cuoco has graced the screen with Sagal. Previously, the two appeared as mother-and-daughter on the ABC comedy 8 Simple Rules.

Now that’s what we call a true family reunion!
