The network announced Tuesday that Moore will guest star on the second-season premiere of White's hit comedy, "Hot in Cleveland." TV Land says the episode will air in January.
Moore's guest appearance will be the first time she and White have acted on screen together since "The Mary Tyler Moore Show" went off the air more than three decades ago. On that classic sitcom, Moore was an assistant news producer at a TV station, while White played the host of a homemaking show.
On "Hot in Cleveland," White plays a landlady to three eccentric best friends from Los Angeles who move to Cleveland. It also stars Valerie Bertinelli, Jane Leeves and Wendie Malick.
