American actress Suzanne Somers has celebrated her 73rd birthday by posting a nude photo of herself in Palm Springs, California.

The former Three's Company and Step by Step star captioned the image — which shows her crouching behind some plants — with: "Here I am in my Birthday Suit!!!"

Somers, who also owns beauty brand Suzanne Organics, was disgnosed with breast cancer 20 years ago and told People magazine in August that the illness had been a wake-up call for her.

Following her diagnosis she decided to drastically alter her lifestyle in a bid to live more healthily.

"I just thought, I'm going to win this my way, I'm going to change my life. I'm going to eat until my life defends upon it," she said. "There's not one chemical in our house and you can feel it when you walk in."

Somers told People her illness also led to the development of Suzanne Organics, which she was "real proud of".
