The actress, 52, said at 90's Con in Daytona Beach, Florida over the weekend that, in hindsight, she's not happy she returned for the "Beverly Hills, 90210" reboot that aired on The CW from 2008 to 2013.

"I wish I hadn't done it. No offense to them," she said, according to People.

"The producer was a friend of a friend, and I remember he came over in my living room, sat me down, [billed it as] this chance of a lifetime," Garth explained. "He asked me to do it, and I didn't know how to say no then."

She added, "But the people were very nice and all the best to them."

Garth played Kelly Taylor in "Beverly Hills, 90210." The show, which also starred Jason Priestley, Tori Spelling, Shannen Doherty, Gabrielle Carteris, Brian Austin Green, Ian Ziering and Luke Perry, ran from 1990 to 2000 on Fox.

Like the original series, "90210" followed a group of rich friends transitioning from high school in Beverly Hills to adulthood. The reboot starred Rob Estes, Shenae Grimes, Tristan Wilds, Ryan Eggold, Jessica Stroup and more.

Garth, Spelling and Doherty all returned for "90210." Garth's character worked as the guidance counselor at the same school in the reboot.

At 90's Con, Garth was joined at the "Beverly Hills, 90210" panel by Green, Carteris, and Ziering, who all also weighed in on the reboot.

"I never wanted to [do it]," Carteris, 63, reportedly said. "I was so shocked they were doing a new show. I was like, is it like, they long so much you're just going to try to reinvent it over and over?"

Green, 51, said, "No offense at all, it's to me, we did 10 years of that show and it's like OK, done."

Almost the entire "Beverly Hills, 90210" cast returned for 2019's "BH90210," where they played heightened versions of their real selves in the present day.

Perry did not participate in "BH90210." He died at age 52 the same year the show came out.

Doherty, who played Brenda Walsh in the franchise, died at age 53 in July. She passed away after a years-long battle with cancer.

The "Beverly Hills, 90210" cast members who were at 90's Con paid tribute to Doherty during their panel.

"She's to me an amazing example for everyone of [how] she put her own challenges and her own health things aside and really wanted to share with everyone the experience of all of it, and it was incredibly brave," said Green.

"Going through something as difficult as that and being open to being completely transparent and sharing with everyone is brave," he added.
