Following a fight with dementia, Sally Kellerman, who was nominated for an Oscar for her role in the Robert Altman classic "M*A*S*H," passed away on Thursday. She was eighty-four.

"It is with great sadness that we report the passing of our beloved Sally Kellerman, who died peacefully in her sleep early this morning, February 24," said the post on her official Facebook page announcing her death. Throughout the course of her 60-year career, she gifted us with countless hours of magical TV and film, not to mention her amazing singing. Though her performances will always be remembered, she will be missed. RIP, sweet lady."

An accompanying video featured Kellerman singing "Could I Leave You?" from the musical "Follies."
She was born in Long Beach, California, on June 2, 1937, and went to Hollywood High, where she fell in love with acting. She had a recording contract with Verve Records when she was a teenager, but she decided against going into music as a career.

Along with Kellerman, Jack Nicholson, Robert Blake, Shirley Knight, and Dean Stockwell, the cast of "Look Back in Anger" on stage included several future stars in her first gig.

She debuted in a 1957 movie called "Reform School Girl" and on television in a 1959 episode of "Playhouse 90."

Over her extensive TV career, she starred in shows such as "Bachelor Father" (1960), "Surfside 6" (1961), "The Twilight Zone" (1963), "The Adventures of Ozzie and Harriet" (1963), "The Many Loves of Dobie Gillis" (1963), "My Three Sons" (1963), "The Alfred Hitchcock Hour" (1965), and a well-known "Star Trek" (1966) episode titled "Where No Man Has Gone Before."

Following her appearance in the popular film "The Boston Strangler" (1968), she was cast as Maj. Margaret "Hot Lips" Houlihan in the 1970 film adaptation of "M*A*S*H," a character that Loretta Swit eventually played on television.
