Katherine Helmond — most famous for her feisty role on “Who’s the Boss?” — has passed away.
The 89-year-old died on February 23, according to her talent agency. They did not go into detail about what happened.
Helmond played Mona Robinson, the man-crazed mom, on the popular ABC sitcom. The series ended in 1992 after eight seasons. She was nominated twice for an Emmy for her role, as well as one TV Land Award, and finally walked away with a Golden Globe for Best Supporting Actress.
“Who’s the Boss?” star Alyssa Milano reacted on Twitter, writing, “My beautiful, kind, funny, gracious, compassionate, rock. 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 TV star also appeared in several shows including “Soap,” “Coach,” “Everybody Loves Raymond,” and more.
She married two times throughout her life and has no children.
