Jennie Garth And Tiffani Thiessen Still Not On Speaking Terms

Former "Beverly Hills, 90210" cast mates Jennie Garth and Tiffani Thiessen used to be best friends off-screen, but according to Us Weekly, somewhere along the line things soured.

Thiessen joined the cast of "90210" in 1994 as bad girl Valerie Malone, filling the void created by Shannen Doherty's much-publicized departure, and she and Garth became close friends off-set -- with Thiessen even serving as a bridesmaid at Garth's wedding to (soon-to-be ex-husband) Peter Facinelli.

But the two are no longer BFFs and haven't been for some time, a source told the magazine. The source recalls a 2009 party where Garth wouldn't even look at Thiessen when she said hello to her.

According to the insider, Garth finally snapped, telling Theissen, "OK? You got me?" The eavesdropper said that Thiessen appeared sheepish as Garth just turned and walked away.

What transpired to end their friendship remains unknown, and the two still aren't on speaking terms to this day.

And when asked to comment on Garth's divorce, Thiessen sidestepped talking about her former friend, telling OK! magazine, "Obviously, divorce is not easy on anybody. It’s important for the kids to be okay. So I can’t imagine that they probably aren’t thinking of them first. Hopefully that’s the case."

News of the falling out comes after original "90210" cast members Jennie Garth, Shannen Doherty and Tori Spelling seemed to have finally ended their 20-year rivalry, with Doherty recently expressing sympathy for Garth during her divorce.

Doherty told People magazine that since the two worked together on the new "90210," which airs on the CW, they were able to put their past and differences aside. "We were able look at each other as grown women and really acknowledge that we like who the other person was now, as adults."
