Penny will be meeting her family in Season 10 of “The Big Bang Theory,” with Katey Sagal (“Sons of Anarchy”) as her mom and Jack McBrayer (“30 Rock”) as her brother, the writers announced at San Diego Comic Con Friday.

Steve Molaro made the announcement during the “Big Bang Theory” writers panel, saying, “We are finally going to meet more of Penny’s family. We’re going to be meeting Penny’s mom and her brother in the first episode back.”

Season 10 of CBS’ perennial hit comedy marks the tail-end of a three-year renewal for the show announced back in 2014.

The show stars Jim Parsons, Johnny Galecki, Kaley Cuoco, Simon Helberg, Kunal Nayyar, Mayim Bialik and Melissa Rauch.

Chuck Lorre, Steve Molaro and Bill Prady are executive producers. The series comes from Chuck Lorre Productions, Inc., in association with Warner Bros. Television. Lorre and Prady created it.
