Tiffani, 45, revealed why she’s bailing on the new series at The Secret Life of Pets 2 premiere in Los Angeles on Sunday, June 2.
Her non-involvement in it is nothing personal, strictly business. It centers around her contractual obligations on the Netflix series Alexa and Katie.
"I'm actually shooting season three of Alexa and Katie right now. So I am working at the moment and busy," she shared with Entertainment Tonight. "I'm literally in the middle of my season, and I go 'til September."
"I don't know too much about it but I know people are going to be excited,” Tiffani added about the upcoming series.
Tiffani joined the original run of the show in the fifth season shortly after Shannen Doherty’s departure. She remained as a main cast member for the next four years.
90210’s reunion series, simply titled BH90210, will premiere August 7 on FOX. Several of the show’s original stars will return including Shannen, 48, Tori Spelling and Jennie Garth.
According to Variety, the cast will play "heightened versions of themselves" in an irreverent drama "inspired by their real lives and relationships with each other."
