Actress Suzanne Somers, best known for playing a bumbling blonde on “Three’s Company,” died early Sunday morning after a decades-long battle with cancer. She was 76.

Somers’ longtime publicist confirmed her death to Page Six.

“Suzanne Somers passed away peacefully at home in the early morning hours of October 15th. She survived an aggressive form of breast cancer for over 23 years,” said R. Couri Hay. “Suzanne was surrounded by her loving husband Alan, her son Bruce, and her immediate family.”

The “Step by Step” star was due to turn 77 on Monday.
