Riverdale and 90210 fans are still in shock over the news of actor Luke Perry's stroke, which he suffered in his California home on Wednesday morning, and some of his co-stars are sending out their support online. BuzzFeed and USA Today note the big names from both shows who are rallying behind the 52-year-old actor. Molly Ringwald, who plays Perry's former wife on Riverdale, posted on Twitter a simple "Sending my love" to her onscreen ex, with co-stars Skeet Ulrich, Lili Reinhart, Madchen Amick, and Cole Sprouse adding their own messages. On the 90210 side, Ian Ziering posted a photo of himself giving a smooch to Perry, who played Dylan McKay on the show, while Shannen Doherty, who played Brenda Walsh, one of Dylan's loves, posted a pic of them embracing, with the message: "My friend. Holding you tight and giving you my strength. You got this."
EW.com rounds up words of encouragement from other celebrities, including Billy Baldwin, Rosanna Arquette, and Kristy Swanson. More support came from another star who's actually been where Perry is now: Sharon Stone, who survived a stroke in 2001, per People. "I wish him all the best, because you can come all the way back even from the edge, from the worst things, I'm here to tell you," the 60-year-old actress told Extra Thursday night at a charity event. Perry is still in the hospital, his rep told People, but there's been no update on his condition. (Read more Luke Perry stories.)
