According to PEOPLE, the actress died "peacefully at home" while surrounded by her loved ones.

The actress Suzanne Somers, widely known for her work on Step by Step and Three's Company, has passed away.

Sunday morning, Somers passed away, according to PEOPLE. On Monday, she would have turned 77.

"Suzanne Somers died quietly at home on October 15 in the early hours. She overcame an aggressive form of breast cancer for over 23 years, according to a statement released by Somers' longtime publicist R. Couri Hay on behalf of the actress' family.

The statement said, "Suzanne was surrounded by her devoted husband Alan, her son Bruce, and her immediate family. On October 16, her family came together to celebrate her 77th birthday. Rather, they will honour her remarkable life and express their gratitude to the millions of admirers and followers who cherished her.

Hay also said to PEOPLE in a different statement that Somers' last residence was "one of her dreams" and that it was a "beautiful house."

Her publicist stated, "She was very engaged right to the end and had all these plans and she was always working and dreaming and had brought her family into the business." The publicist also added that she had recruited her grandchildren and stepchildren into the firm.

Hay reports that a memorial service will be held in November and that a private family burial will occur this week.

Somers told PEOPLE that she was excited to celebrate the big day with her loved ones before it was her birthday.

The actress and businesswoman revealed that her "nearest and dearest"—her "loving husband Alan [Hamel], our three children, Leslie, Stephen, and Bruce, [his wife] Caroline, plus our six magnificent grandchildren”—would be present on her birthday.

Hamel, who married Somers in 1977, commended his wife's tenacity in the same interview.

The former TV personality told PEOPLE, "Suzanne and I just got back from the Midwest, where Suzanne had six weeks of intense physical therapy." "Even after fifty years of marriage, Suzanne's incredible perseverance and dedication continue to astound me."

Somers revealed that her breast cancer has returned for the first time since her initial diagnosis in 2000 in a moving Instagram post in July.

She added, "As you know, I had breast cancer two decades ago, and every now and then it pops up again, and I continue to bat it down," next to a picture of herself and Hamel, 87. To battle it, I have employed the most effective conventional and alternative therapies. For me, this is not unfamiliar ground. I am a fighter who knows how to put on my combat armour."

The actress also thanked Hamel and her entire family for their unwavering support in the same tweet.

She went on, "Alan has supported me the entire time." "The amount of what he has done for me is beyond words. We've never been closer, if that's even possible. My amazing family has done so much in keeping the business going so you can continue to have access to all the lovely things. They have been so supportive. I appreciate your unwavering love and support. I love you, and it only matters who you love and who loves you."

Somers featured as Sheriff Hildy Granger on She's the Sheriff (1987–1989), in addition to her well-known performances as Chrissy Snow on Three's Company (1977–1981) and Carol Foster Lambert on Step by Step (1991–1998).

The actress was also well-known for her commercial endeavours in the health and beauty industry, including the ThighMaster training equipment, and for her books, of which she wrote over 25 and which became a New York Times best-selling author.

Hamel, her 57-year-old son Bruce, her stepchildren Stephen and Leslie, and her six grandchildren make up Somers' "blended family."
