What is the name of Frasier Crane's ex-wife who appeared on Cheers?

Frasier Crane’s ex-wife who appeared on Cheers is Lilith Sternin. Bebe Neuwirth played the character, a highly educated psychiatrist whose cool, severe manner made her an especially memorable match for Frasier.

Lilith first appeared in the season-four episode “Second Time Around” as a date for Frasier. The encounter goes badly, but the two later reconnect and begin a relationship. They eventually live together, marry, and have a son, Frederick. Their relationship became one of Cheers’ recurring storylines, balancing intellectual compatibility with constant emotional friction.

Lilith’s marriage to Frasier is complicated by her affair with Dr. Louis Pascal during Cheers’ final season. She temporarily leaves Frasier, but the storyline ends with her returning to Boston. By the beginning of the spin-off Frasier, their divorce has been finalized, and Lilith continues to appear as Frasier’s formidable former spouse. She is sometimes confused with Diane Chambers or Rebecca Howe, but both women had different relationships with Frasier and were never his wife.
