Kirstie Alley is set for another major reunion on her new U.S. TV comedy - John Travolta has signed on for a guest appearance. The actress will team up with her former Cheers castmates Rhea Perlman and George Wendt on Kirstie - and now Alley's Look Who's Talking co-star has announced he will be dropping by. On the show, Alley will play a Broadway star who reconnects with the son she gave up for adoption. Travolta will play a stagehand on her character's Broadway show who briefly dated the actress. A statement from Travolta reads: "I'm excited about working with Kirstie again... It's always a treat to be surrounded by people you respect so much both personally and professionally." Kristin Chenoweth, Kristen Johnston, Cloris Leachman and former Seinfeld stars Jason Alexander and Michael Richards will also feature on Kirstie, which will debut in the U.S. in December (13).
