Shannen Doherty found herself overcome with emotions as she tearfully reminisced about her late co-star and dear friend, Luke Perry.

At MegaCon Orlando's Beverly Hills, 90210 panel on Saturday, the Hot Seat star and Jason Priestley shared memories of their late co-star, who tragically passed away at the age of 52 in March 2019 due to a stroke.

During the discussion, Doherty,52, became visibly emotional when the Call Me Fitz star, 54, brought up Perry's name.

Prompted by the mention of her dear friend, Doherty teared up and, initially using her left hand to wipe away tears, eventually left her seat to fetch a tissue for further emotional relief.

“It was shocking,” said Doherty, whose 90210 character, Brenda, shared a romance with Dylan, played by Perry.

She added, “I have a very visceral reaction whenever someone brings up Luke because as someone with cancer — and a really horrible cancer at stage 4 — I thought I would be the first to go. So when it was Luke, it really just sent me for a tailspin.”

Speaking at MegaCon, Doherty shared that during the filming of the '90s teen drama, she and Perry had a strong bond, but she acknowledged that “there were moments where we were not so close” in the years following the show's conclusion in 2000.

“But later we became extremely close,” she counted.

The Heathers star revealed, “So to lose him as our relationship was just sort of flourishing as friends, and our respect and admiration for each other was coming to its fullest potential … it was just very hard.”

Doherty continued, “I think it continues to be hard for all of us, and when we do cons or any signings and it’s all of us there, Luke’s presence is missed,” adding, “There’s a hole, for sure.”

At the same time, Priestley pondered the influence Luke Perry had on the cast of Beverly Hills, 90210.

He said, “Luke was a huge part of our show,” adding, “He was a total joker. He would come to work, and always break the tension, and make everybody laugh. But then he was also incredibly professional, and always there, and always committed to what he was doing.”

“We were all close as a group, but Luke was close with everybody within the group,” recalled.

He shared, “He was incredibly kind and considerate and a lot of things that I think when people think about TV stars or movie stars or heartthrobs wouldn’t pair those two up.”

Priestley concluded, “He was beautiful,” adding, “We all miss him very much, to this day.”
