Jennie Garth details her falling-out with ‘90210’ co-star Tiffani Thiessen

Jennie Garth is no longer in touch with her “Beverly Hills, 90210” co-star Tiffani Thiessen after their infamous falling-out.

“Tiffani and I didn’t have such a happy ending with our friendship,” Garth writes in her new memoir, “I Choose Me,” which is out now.

She adds, “We’re no longer close.”

The two met in 1994, when Thiessen, 52, joined the cast of “90210” in the fifth season as the cunning Valerie Malone.

“Her character brought tension, complexity, and a fresh energy to the ensemble,” Garth writes, admitting that she immediately “felt threatened and competitive” with the “Saved by the Bell” alum,

“just as I had with many beautiful co-stars before.”

Garth quickly realized the negative pattern she was repeating, apologized to Thiessen, and “that’s how we became best friends during her years on ‘90210.’” The two hit it off so well that Thiessen

served as a bridesmaid at Garth’s wedding to Peter Facinelli in 2001.

The two maintained their friendship after the show ended.

When Garth, 54, began working on “What I Like About You,” an actor named Brady Smith joined the show for one episode. Garth “immediately knew” Smith was “perfect” for Thiessen.

“He was tall and handsome and from Texas,” she writes, “and I just had the feeling they would hit it off. I called her right away and told her to come down to the set to meet this cute guy … Cut to:

They’ve been married for years with a gorgeous family.”

Garth has never given a full reasoning behind the falling-out, although the two have run into each other since, at an audition and a dinner party,
