Charmed star Rose McGowan took to Instagram with a compilation of photos of the stars together, and penned: "Shannen Doherty had the heart of a lion. Passion for craft is often mislabeled as trouble. Shannen was passion. I met her in the 90s and was awed."
"Getting to really know her later in life, a beautiful gift. This woman fought to live. Shannen knew how to be a star because she was one since childhood. Her work ethic inspiring to the end. Shannen's great love for directing, for acting, Holly, her friends, her parents, dog and her beloved fans was legendary. Our lives had been intertwined in a unique way."
She continued: "We laughed at dark forces who wanted us to hate each other, instead we chose love and respect. A soft-hearted badass as there ever was. A force of energy that will live forever in hearts. May angels and God carry her to the holy kingdom where she is healthy, young and wild forever. Rest now warrior, we will never forget you dear sister."

"I am absolutely heartbroken over the passing of Shannen Doherty. When I was first diagnosed with breast cancer I remembered how she bravely let the world into her journey and reached out to her."

Looking back on the last text she sent me just a couple months ago, she asked how I was doing and if she could do anything for me...."

Cancer is really [expletive] scary and Shannen faced it with such dignity, strength and grace.
