Jennie Garth Shares the Beverly Hills, 90210 Cast Text Chain's Heartbreaking Reaction to Shannen Doherty's Death: 'No More Loss'

Shannen Doherty's Beverly Hills, 90210 castmates are still reeling from her loss.

On the first episode of her podcast since Doherty's death on July 13, Jennie Garth shared with fans how the cast of the hit '90s show reacted to the news over the weekend, as she revealed that they were all chatting in a group chat.

"Jason [Priestley], of course, was the first one to reach out to everybody and just, you know, say, I love you guys, and this is insane," Garth, 52, said on the July 19 episode of I Choose Me with Jennie Garth. "And no more loss."

"I think that's one of the hardest parts for me is that it's now – it's 2 people from our original cast [who have died]," Garth said, referring to Luke Perry, who died in 2019 after suffering from a stroke.

The What I Like About You alum said she's been imagining "a group shot [of the cast]," which also includes Brian Austin Green, Ian Ziering, Gabrielle Carteris and Tori Spelling, "and if you can imagine that image of that person in the group shot fading, and to disappear. Like, it's just — I can't really wrap my head around it."

Garth said she felt "like someone punched me in the stomach" after hearing the news that Doherty had died at 53 after her years-long battle with cancer.

The actress' longtime publicist, Leslie Sloane, confirmed the news to PEOPLE on July 14. "The devoted daughter, sister, aunt and friend was surrounded by her loved ones as well as her dog, Bowie. The family asks for their privacy at this time so they can grieve in peace," Sloane said in a statement.

Garth was "shocked" to hear the news, "and then I was pissed at myself for being shocked."

"I was like, so mad, you know, I was, bargaining and saying, 'Why her? Like, why not me?' And I know.... I don't know anything actually, but there were so many feelings. I was angry — angry at her circumstances, at cancer. At the world for taking her away from her mom and her family and her dog. She loved Bowie so much."

She continued, "It's crazy because we all knew she was sick. The whole world knew that, and I don't know why, but I just thought she would get better. I thought she would kick it. She's the strongest woman around and I just never thought that this would happen."

On Sunday, Garth paid tribute to her former costar with a long message on Instagram, remembering their "connection" outside of the spotlight.

"I am still processing my tremendous grief over the loss of my long time friend Shannen, the woman I have often described as one of the strongest people I have ever known. Our connection was real and honest. We were so often pitted against each other but none of that reflected the truth of our real relationship which was one built on mutual respect and admiration," Garth wrote.

"She was courageous, passionate, determined and very loving and generous. I will miss her and will always honor her deeply in my heart and in my memories," she added. "My heart breaks for her family and Bowie 💔."
