Former Seinfeld stars Jason Alexander and Michael Richards are to reunite on actress Kirstie Alley's new TV sitcom.

The new show, Kirstie, will also bring another classic TV pairing - Alley's Cheers co-star Rhea Perlman is also among the cast.

Announcing the casting news on Thursday, Alexander said: "It is a strange and wonderful thing to be working on a brand new show yet surrounded by familiar faces and friends. I'm looking forward to a fun and fabulous time."

Alley will play Broadway star Madison Banks in the new TV comedy.
