Garth took to Instagram on Tuesday to share a cute photo of her and Spelling getting cozy under a pink and white blanket.
"J+T = BFF," the 50-year-old penned in the caption, referring to the pair's 30-year friendship.
In the comments, fans praised Garth and Spelling, 49, for their "beautiful friendship."
"Beverly Hills queens!" commented a follower.
"Two of my fave people on the planet!" shared someone else. "This is BFF goals!"
"I couldn't love this more, this is so cute!" added another.
"You guys are so adorable. Love your beautiful friendship so much!" wrote a fan.
The duo met on the set of "Beverly Hills, 90210," which premiered in 1990. Over the next decade, Spelling and Garth played on-screen best friends. And although the iconic drama ended in 2000, the pair have kept up their real-life friendship.
Moreover, almost 10 years later, Garth and Spelling reprised their "Beverly Hills" roles in the CW reboot "90210." In 2014, the pair reunited once more for "Mystery Girls."
"It’s a true friendship," the "True Tori" star said on "The View" while promoting the ABC series with Garth. "We were friends when we were in teens. And you never know. In our 40s, you don’t have those friendships that are lasting and ours have."
Garth added that the pair have a "a lot in common" such as "being moms."
"... We have had a close friendship, she’s one of my best friends, for 30 years," Spelling revealed in 2019. "And we have gotten to the point in our lives where we just want to work together. Our kids are friends, and we want our families together all the time, so we wanted to develop something together. And that’s when we started talking about, 'Was it the right time to do something with 90210 finally?'"
