Luke Perry has died in California at the age of 52, less than a week after suffering a massive stroke.
His publicist said Perry died surrounded by his family and friends.
Perry rose to fame on Beverly Hills, 90210 and had been starring as Fred Andrews on the CW show Riverdale.
He was taken to hospital on Wednesday in Los Angeles, where he had been shooting scenes for Riverdale at the Warner Bros film lot.
Perry's children, Jack and Sophie, fiancée Wendy Madison Bauer, ex-wife Minnie Sharp, mother Ann Bennett, step-father Steve Bennett, and his siblings, Tom Perry and Amy Coder, were with him when he passed, publicist Arnold Robinson said in a statement.
"The family appreciates the outpouring of support and prayers that have been extended to Luke from around the world, and respectfully request privacy in this time of great mourning," Mr Robinson said.
Perry, a native of Ohio, was famous for starring in Beverly Hills 90210 from 1990 to 2000. A reboot of the series was also announced on Wednesday, though it was not clear whether Perry planned to make any guest appearances.
Former 90210 co-star Shannen Doherty - who played Perry's love interest on the show - told Entertainment Tonight on Sunday in an emotional interview that she had been in touch with him after his stroke.
"I can't talk about it here 'cause I will literally start crying but I love him and he knows I love him. It's Luke, and he's my Dylan."
Shannen Doherty says she's "struggling" with the loss of the man who, with her, brought to life one of TV's most iconic fictional teen couples on "Beverly Hills, 90210."
"Yesterday morning I got a phone call that devastated me," Doherty wrote on Instagram. "I'm struggling with this loss and am having a hard time with my thoughts. But, my heart goes out to his family and friends who were blessed by his light in their (and mine) lives."
On Thursday morning, Priestley posted an Instagram tribute to Perry, featuring two snaps of the pals — one throwback photo taken during their 90210 days alongside a more recent picture.
“It’s taken me a couple of days to figure out how to write this,” Priestley began. “My dear friend of 29 years, Luke Perry, was one of those truly special people who really cared… Luke was not only a star, he was an incredibly bright light that was extinguished far too soon… and that is why I, and so many others, are in so much pain today.”
Kristy Swanson, Luke Perry's co-star in the 1992 Buffy The Vampire Slayer movie, remembered the late Beverly Hills, 90210 actor in a pair of emotional Instagram posts with black and white photos from the set.
"I abruptly woke at 4:30am thinking about you Luke & I couldn’t go back to sleep, then 5 hours later I hear you are gone," Swanson wrote on Monday, the day Perry died, alongside a photo of the two together. "The tears won’t stop & they never ever will. You were that guy, that forever friend, we always had each others back & I will always remember you this way..."
Swanson later shared a candid behind-the-scenes photo on Thursday.
Luke Perry‘s fiancée broke her silence after the actor’s death.
Wendy Madison Bauer was in a relationship with the “Beverly Hills, 90210” star for nearly 12 years, but the couple kept their romance private.
“I want to express my gratitude to everyone for the outpouring of love and support,” Bauer, 44, told People on Saturday. “The countless, heartwarming stories of Luke’s generosity and kindness have been a great source of solace during this difficult time.”
“The past 11½ years with Luke were the happiest years of my life, and I am grateful to have had that time with him. I also want to thank his children, family, and friends for their love and support,” Bauer continued. “We have found comfort in one another and in the knowledge that our lives were touched by an extraordinary man. He will be dearly missed.”
Had Perry and Bauer tied the knot, she would have been his second wife. The “Riverdale” star amicably divorced his first wife, Rachel “Minnie” Sharp, in 2003.
