“The DUI did not break up our friendship. I was very supportive of Shannon for months after her DUI,” Tamra began during a July 11 interview with Decider.  “If you go back to BravoCon, she did an interview and said that [Vicki Gunvalson] and I were the people who supported her the most. I was truly worried for years that something like this was going to happen to her. I thought it would be a huge wake up call to her, and she would finally stop drinking. But that did not happen.”

While Shannon has suggested that Tamra abandoned their friendship after her arrest, Tamra made it clear that their current estrangement is “because of Shannon.”

“She did something that I can’t really give away. It eventually led me to quit Tres Amigas and cut her out of my life. I had to do it for my own peace of mind. I had to make myself a priority and not let her overly dramatic neurotic behavior affect me anymore,” Tamra explained. “I didn’t want to enable that behavior as well.”

As for Shannon’s claim that she was “finding out who [her] true friends [were]” amid season 18, Tamra shaded her castmate’s “lies.”

“Don’t insinuate I wasn’t your true friend. I was the one that was there for you for 10 years, even after you’d stopped talking to me for 2 years, when you had no use for me,” she stated.

While Shannon has struck up a friendship with Jennifer after her falling out with Tamra, Tamra believes she did so only because she needed an ally on the show.
