Doherty, who was first diagnosed with breast cancer in 2015 , "was surrounded by her loved ones as well as her dog, Bowie." She was remembered as a "devoted daughter, sister, aunt and friend."

Many of the late star's former 90210 co-stars joined spelling in paying tribute to Doherty online. Sharing two throwback photos of herself and Doherty, Garth wrote on Instagram , "I am still processing my tremendous grief over the loss of my long time friend Shannen. The woman I have often described as one of the strongest people I have ever known. Our connection was real and honest. We were so often pitted against each other but none of that reflected the truth of our real relationship which was one built on mutual respect and admiration."

"She was courageous, passionate, determined and very loving and generous," Garth, who portrayed Kelly Taylor on the show, continued. "I will miss her and will always honor her deeply in my heart and in my memories. My heart breaks for her family and Bowie."

Jason Priestley, who played Doherty's on-screen brother Brandon Walsh, wrote on Instagram , "Shocked and saddened to hear about the passing of my friend Shannen. She was a force of nature and I will miss her. Sending love and light to her family in this dark time."
