All of Luke Perry's '90210' Costars Who Have Paid Tribute to Late Actor After His Death
The Cast of '90210': Where Are They Now?

Jason Priestley and Tiffani Thiessen are the latest to honor their late costar with tributes on social media.

Luke Perry's "Beverly Hills, 90210" family is heartbroken after the actor's sudden death on Monday, following a stroke. The actor was only 52 and is survived by his two children, Jack, 21, and Sophie, 18, his kids with ex-wife, Rachel Minnie Sharp.

The star is most synonymous with his role on the primetime soap, where he played the effortlessly cool Dylan McKay throughout most of the show's run. While he had a recent career resurgence thanks to his work as Fred Andrews on "Riverdale," he'll always be Dylan for a certain set of '90s kids.

As news of his death spread through Hollywood, his former "90210" costars began posting tributes to the late Perry on social media. Many also shared heartfelt statements via their publicists, as they remembered the man with whom they spent a lot of their young adult lives.

While a revival of "90210" is coming to Fox this summer with Jason Priestley, Jennie Garth, Ian Ziering, Gabrielle Carteris, Brian Austin Green and Tori Spelling, neither Perry or Shannen Doherty were confirmed to be part of it.

It took Priestley a few days to find the right words about his longtime friend, sharing his message on Thursday, March 7.

"It's taken me a couple of days to figure out how to write this... My dear friend of 29 years, Luke Perry, was one of those truly special people who really cared," he wrote. "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... If you had the good fortune to know Luke, or to have ever crossed his path, I know you are sad today as well... the candle that burns twice as bright only burns for half as long... you burned oh, so brightly Luke... Goodnight Sweet Prince."

Tiffani Thiessen, who played bad girl Valerie Malone in later seasons, also shared her tribute to Perry on Thursday, thanking him for welcoming her so warmly to the cast.

"My heart has been weighing heavy. The loss of a man who started as my co-star but quickly became my friend. He welcomed me on my very first day of #90210 with open arms," she wrote. "A day that was not an easy one for me. I was coming in to a show, a family really, that had been together for over 4 years. But this man took me under his wing and made me feel at home. Made me feel like I belonged in his TV family."

"He was sincere, sweet, warm, kind, professional and funny as all heck," she continued. "And most of all, the definition of a gentleman. Luke, our world has a hole in it now that you aren't here. But heaven definitely gained you as an angel. #RIP #LukePerry #gonetoosoon"

Doherty told PEOPLE that they met up just a couple weeks ago for lunch and were discussing "something special and meaningful for our fans at this stage in our lives."

"I am in shock. Heartbroken. Devastated by the loss of my friend. I have so many memories with Luke that make me smile and that are forever imprinted on my heart and mind," she continued. "Luke was a smart, quiet, humble and complex man with a heart of gold and never-ending well of integrity and love. Luke reached out to me during my cancer journey and we picked right back up, albeit older and wiser, but that connection remained in tact."

Doherty added that Perry "loved his family" and "raved about his kids and how proud he was of them. They were his heart and for him, his biggest accomplishment."

Spelling was equally "heartbroken" and "in utter shock," telling PEOPLE she too felt for the actor's family.

"I'm saddened for his kids whom he adored beyond words. He was so proud of Jack and Sophie," she continued. "Luke was one of the kindest and most humble human beings I've ever known. I'm grateful for the years of friendship we had. He truly was family to me, a protector and a brother. I'm so sorry for the loss that everyone is experiencing."

In another statement, Garth said that Perry "meant so much to so many" and called him "such a very special person." She added, "I share my deep sadness with his family and all who loved him. Such a terrible loss."

Priestley has yet to release a full statement about his death, though he did share a reporter's video of the two of them doing a joint interview together in recent years. He thanked the reporter for sharing it.

Ziering, Carteris, Kathleen Robertson (who played Clare Arnold), Christine Elise (AKA Emily Valentine) and Ashley Tisdale (who had a one-episode appearance on the show's run) all paid tribute on social media as well.
