On Monday (December 5), actress Kirstie Alley’s children, True and Lillie Parker, announced to the world that their mother had passed away.

“We are sad to inform you that our incredible, fierce, and loving mother has passed away after a battle with cancer, only recently discovered,” they wrote. “She was surrounded by her closest family and fought with great strength, leacing us with a certainty of her never-ending joy of living and whatever adventures lie ahead. As iconic as she was on screen, she was an even more amazing mother and grandmother.”

Alley shared True and Lillie with ex-husband Parker Stevenson, who mourned the death of Alley on Instagram.

“Dear Kirstie, I am so grateful for our years together, and for the two incredibly beautiful children and now grandchildren that we have. You will be missed,” he wrote.

While her children did announce that her death was caused by a brief battle against cancer, her rep confirmed to PEOPLE what kind of cancer she had – colon.

We will keep Alley’s children, grandchildren, and all who loved her in our prayers.
