Suzanne Somers, best known for her role in the iconic sitcom "Three's Company," died Sunday at 76, according to her publicist. 

“Suzanne Somers passed away peacefully at home in the early morning hours of October 15th," R. Couri Hay said in a statement. "She survived an aggressive form of breast cancer for over 23 years. Suzanne was surrounded by her loving husband Alan, her son Bruce, and her immediate family. Her family was gathered to celebrate her 77th birthday on October 16th. Instead, they will celebrate her extraordinary life, and want to thank her millions of fans and followers who loved her dearly."

Somers became famous for playing, as she put it, “one of the best dumb blondes that’s ever been done.” 

The star was born Suzanne Marie Mahoney in 1946 and started acting in the late '60s and early '70s when she had smaller roles in the movies "Bullitt" and "Magnum Force." However, Somers got her big break when she was cast for her role as "Chrissy" on "Three's Company" along with the late John Ritter and Joyce DeWitt. Later, Somers made another name for herself as the spokesperson and model for the "Thighmaster" fitness product in the 90s.

Ten years after she was fired from "Three's Company," Somers scored her next big television role, when she was cast on ABC's "Step by Step" alongside "Dallas" alum Patrick Duffy. Similar to the plot of "The Brady Bunch," the sitcom starred Somers and Duffy as Frank and Carol, two single parents who married and blended their families, which consisted of three children each. Somers remained on this show, which was part of ABC's TGIF lineup until it changed networks for its final season, for its entire seven-season run, which ended in 1998.

Somers worked sporadically in television in the years after "Step by Step" ended, including brief forays into talk. She gave Broadway a shot in 2005 with her one-woman show "The Blonde in the Thunderbird"– a reference to her cameo in "American Graffiti" more than 30 years earlier – featuring a collection of stories about her life and Hollywood career, but it closed after less than a week of performances due to poor ticket sales and bad notices. She also competed on season 20 of "Dancing with the Stars" in 2015 alongside her professional partner, Tony Dovolani, placing ninth.

Since her appearance on "Three's Company" and the "Thighmaster" infomercials, she was widely viewed as a sex symbol, even in her later years. She famously survived several battles with severe breast cancer starting in 2000. During her career, she starred in multiple film and television roles and wrote several books, including a personal memoir. 

Somers had just one child, a son, with her first husband, Bruce Somers, named Bruce Jr. After their divorce in 1968, Somers remarried Alan Hamel in 1977 and they stayed together until her death.
