Suzanne Somers and Patrick Duffy brought the quintessential blended American family to life as the stars of the '90s TV sitcom "Step by Step."

Duffy and Somers starred as single parents Frank Lambert and Carol Foster, who fell in love, married and joined their families together. Not only were the newlyweds starting over again as adults, they each had three children and created a new idea of family.

Somers "passed away peacefully at home in the early morning hours of October 15th," her representative confirmed in a statement provided to Fox News Digital. "She survived an aggressive form of breast cancer for over 23 years."

Duffy shared a portrait shot of the late actress and wrote that he was "stunned yesterday by the news" of her death.

He added, "I am not alone in wishing I had one more face-to-face with her and Alan, but had we had that meeting last Friday I would still be yearning for just one more today. It is the painful beauty of our present human reality.

"What strength and support I can muster I send to Alan and Bruce and her family and to her I say; When the stone of your life dropped in this pond you made quite a ripple my friend. Thank you."

"I have been living with cancer for decades now, using the best of alternative and conventional medicine to keep it at bay. Every time that little f---er pops up, I continue to bat it back," she said.
