Elizabeth Hubbard, the star of As the World Turns on CBS, passed away at the age of 89 over the weekend, according to Deadline.

Hubbard’s son, Jeremy Bennett, posted the sad news on Facebook on Monday, April 10. He did not say what caused her death.

Bennett said, “I’m sorry to say with a broken heart mi mum passed over the weekend. Thank you for being an unmovable rock that guided me through life. I will try to honour your memory for as long as I live.”

Hubbard was best known for playing Lucinda Walsh on As the World Turns. For this role, she was nominated for eight Daytime Emmys.

Hubbard won two Daytime Emmys, one for her role as Dr. Althea Davis on NBC’s The Doctors and the other for her role in First Ladies Diaries: Edith Wilson. However, that wasn’t her best performance.

Hubbard was last seen in the digital show Anacostia, which earned her another Daytime Emmy nomination in 2016.
