TMZ

Sheridan died earlier this morning of natural causes, according to TMZ. She appeared in 21 episodes of Seinfeld as Jerry Seinfeld's overprotective mom Helen Seinfeld, who was known for the catchphrase "how could anyone not like him?" She was also a regular on ALF as nosy neighbor Raquel Ochmonek. As TMZ notes, Sheridan was a go-go dancer in the 1950s who dated James Dean, and loved to sing and perform as a one-woman show called "Mrs. Seinfeld Sings." Sheridan's death comes 13 days after the death of Estelle Harris, who famously played George Costanza's mom on Seinfeld. UPDATE: Jerry Seinfeld pays tribute to Liz Sheridan: "Liz was always the sweetest, nicest TV mom a son could wish for," he tweeted. "Every time she came on our show it was the coziest feeling for me. So lucky to have known her."
