Gilbert joining with Galecki on 'Big Bang' arc


Sara Gilbert will reunite with her "Roseanne" hubby Johnny Galecki on Galecki's new comedy series, CBS' "The Big Bang Theory."

Gilbert is set to do a multiepisode arc on the Warner Bros. TV-produced "Big Bang," which revolves around Leonard (Galecki) and Sheldon (Jim Parsons), two socially inept physicists who befriend their new pretty neighbor (Kaley Cuoco).

Gilbert will play a love interest for Leonard. She is a fellow physicist who works with him, and the two attempt to date.

On "Roseanne," Gilbert and Galecki's characters, Darlene Conner and David Healy, had an on-again, off-again relationship until tying the knot in the penultimate season's finale.

Gilbert's role on the long-running ABC sitcom earned her two Emmy nominations.

Gilbert, who gave birth to a girl a month ago, has been recurring on NBC's veteran medical drama "ER," also from WBTV. She is repped by the Gersh Agency and Framework Entertainment.
