When Tiffani Thiessen joined the cast of "90210" in 1994, she admitted to Howard Stern that she didn't have a warm welcoming from the other female actors, which included Tori Spelling and Jennie Garth, but eventually, things got better. So much so that Thiessen and Garth ended up becoming very close.
During her interview, Thiessen mentioned that she was present for the birth of Garth's first child, but revealed that they "had a falling out" and "grew apart." With Stern pressing Thiessen to explain what happened to their friendship, Thiessen remarked, "I was the one who was hurt, let's just say that," and eventually added, "It's funny how our relationship started really rough, and it ended the way it started."
While Thiessen had moved on from her former friends, Garth and Spelling appeared to reignite their old feud when they were judges on "RuPaul's Drag Race" in 2017. According to Us Weekly, when the two women saw that a drag queen dressed up as Thiessen's "90210" character, Garth was heard stating, "As Ti-, how do you say it?" With Spelling then replying, "Just say, 'That which we don't speak of.'" However, after rewatching the episode, Garth shared that it wasn't an attack on her former colleague. "Because I swear to God I was referring to the queen that was playing the character of Valerie and she had a really fancy name like Doolarey, I couldn't remember it and it looked different than it came across."
