Blythe House is Gregory House's biological mother and widow of John House. She is the favorite of his two parents. She was seen in season two's Daddy's Boy, season five's Birthmarks, and season eight's Love is Blind. She is portrayed by actress Diane Baker. She is one of the only characters House does not mind referring to him as "Greg" (the other being Stacy Warner). Blythe returns in Love is Blind to tell her son about her new husband, whom House had always suspected to be his biological father. She later attends her sons funeral in Everybody Dies and says he was a good son.
