One of the stars of the long-running hit CBS comedy “The Big Bang Theory” is expanding her relationship with the studio behind the show.

Variety reports that Mayim Bialik and her recently launched Sad Clown Productions signed an exclusive multiyear production deal, including a talent holding provision for Bialik’s acting services, with Warner Bros. TV.

“Bialik is bringing on former Chuck Lorre Productions exec Mackenzie Gabriel-Vaught to head development for her new shingle,” Variety reports. “The actress is following in the footsteps of ‘Big Bang Theory’ co-stars Kaley Cuoco, who inked a multi-faceted deal with WBTV back in July, and Jim Parsons, who has an overall deal at WBTV via his That’s Wonderful Productions banner.”

Variety adds: “In her new role with Bialik, Vaught will be responsible for developing and producing projects for broadcast, cable, streaming and digital platforms via multiple WBTV Group divisions.”

In a statement, Bialik said: “WB has been my creative home for over a decade and I’m thrilled to be continuing my relationship with them as I develop projects as an actor and a producer. After working with Mackenzie during my entire time at ‘The Big Bang Theory,’ I have grown to respect and value her humor, candor, intelligence, and professionalism. There’s no one else I would rather start this new phase of my career with than Mackenzie and I can’t wait to start showing what we can do together.”
