'Who's The Boss?' Star Katherine Helmond Dies At Age 89

LOS ANGELES (CBSLA) – Renowned film and television actress Katherine Helmond has passed away at age of 89.

Helmond, best known for her roles on the hit shows "Who's the Boss?" and "Soap," died Feb. 23 after suffering complications from Alzheimer's disease, her talent agency told The Hollywood Reporter Friday.

She won a Golden Globe and scored two Emmy supporting-actress nominations for her performance as Mona, the man-crazy mother of Judith Light's character on "Who's the Boss?" She appeared in all eight seasons of the show.

Helmond received four best-actress Emmy nominations for her work on "Soap," a sitcom parody of the daytime soap world that also starred Billy Crystal, Robert Guillaume and Richard Mulligan.

Helmond's "Who's the Boss?" co-star Alyssa Milano remembered her Friday.

"My beautiful, kind, funny, gracious, compassionate, rock," Milano tweeted. "You were an instrumental part of my life. You taught me to hold my head above the marsh! You taught me to do anything for a laugh! What an example you were!"

The Texas native also had recurring roles on the sitcoms "Coach" and "Everybody Loves Raymond," for which she was nominated for an Emmy as best guest actress in 2002.

On the big screen, she appeared in the Terry Gilliam films "Time Bandits," "Brazil" and "Fear and Loathing in Las Vegas." Helmond also provided the voice for Lizzie in the Disney/Pixar "Cars" films.

Helmond began her career on stage, and she earned a Tony nomination for her work in "The Great God Brown" in 1973.
