Luke Perry Dead at 52, Hollywood Reacts with Social Media Tributes

Hollywood is in mourning after the shocking death of Luke Perry.

The "Beverly Hills, 90210" and "Riverdale" star passed away on Monday morning at St. Joseph's Hospital in Burbank, days after suffering a "massive" stroke at his Los Angeles home, reports TMZ. A rep for the actor confirmed his death.

The actor is survived by his two children, Jack, 21, and Sophie, 18, his kids with ex-wife, Rachel Minnie Sharp.

Perry's career began in the late '80s, with appearances on "Another World" and in the Twisted Sister music video for "Be Chrool to Your Scuel," before his big break as Dylan McKay on "90210." He appeared on 199 of the show's 293 episodes in a role that quickly made him a teen heartthrob of the '90s. He would also star in the "Buffy the Vampire Slayer" film, and on shows like "Oz" and "John In Cincinnati" before being cast as Archie's father, Fred, on "Riverdale."

As news of his passing spread, his former costars and Hollywood fans all shared their condolences online. Ian Ziering shared a photo of the two of them together, writing, "Dearest Luke, I will forever bask in the loving memories we've shared over the last thirty years. May your journey forward be enriched by the magnificent souls who have passed before you, just like you have done here for those you leave behind. God please give him a seat close to to you, he deserves it."

Leonardo DiCaprio, who worked with Perry in Quentin Tarantino's upcoming "Once Upon a Time In Hollywood," also honored him online. "Luke Perry was a kindhearted and incredibly talented artist," he wrote. "It was an honor to be able to work with him. My thoughts and prayers go out to him and his loved ones."

Molly Ringwald, who played his estranged wife on "Riverdale, also wrote, "My heart is broken. I will miss you so much Luke Perry. Sending all my love to your family." The show's creator, Roberto Aguirre Sacasa, also tweeted: "So heartbroken about Luke. He was a father, brother, friend, and mentor. Each night before he had to shoot a scene, he'd call me and we'd talk about...everything. I will miss those calls. And my heart goes out to all his family and friends."

"We are deeply saddened to learn today about the passing of Luke Perry," read a statement from the "Riverdale" showrunners and crew. "A beloved member of the Riverdale, Warner Bros. and CW family, Luke was everything you would hope he would be: an incredibly caring, consummate professional with a giant heart, and a true friend to all. A father figure and mentor to the show's young cast, Luke was incredibly generous, and he infused the set with love and kindness. Our thoughts are with Luke's family during this most difficult time."

The actor's "Buffy the Vampire Slayer" costars Kristy Swanson and David Arquette also left touching tributes. See more below, we'll update this post as more come in.
