For the most part, the Tres Amigas seemingly had a solid friendship that none of their other RHOC co-stars could break. While not even Kelly Dodd could demolish Shannon, Vicki, and Tamra, Bravo came close to doing so after a cast shakeup in 2020.

In January 2020, Vicki announced she was leaving Housewives after 14 years of being an OG cast member. One day later, Tamra followed suit and announced on Instagram that she would also be exiting RHOC after 12 seasons. Shannon, however, kept her spot right where it was at.

Vicki and Tamra’s exits ultimately affected the Tres Amigas’s dynamic. In March 2020, fans discovered just how bad things became when Tamra seemingly responded to Shannon’s budding friendship with their former co-star Kelly Dodd.

Days after Shannon posted a photo with her, Kelly, Shannon’s boyfriend, John Janssen, and Kelly’s husband, Rick Leventhal, Tamra reacted on Instagram in what seemed like a shady message towards Shannon before she and Vicki ultimately unfollowed their friend on Instagram.

“Fake friends are like shadows. They follow you in the sun but leave you in the dark,” the Vena CBD founder posted in March 2020 (via People).

In April 2020, Tamra addressed her and Shannon’s issues on Entertainment Tonight. The fitness guru accused Shannon of treating her like she was no longer “important to her” once she was no longer on RHOC.

During a separate interview with the outlet in October 2020, Shannon denied ignoring Tamra and Vicki because of the change in their Real Housewives status. When asked why she remained mum about the drama, Shannon said she refused to “sink down” to their level.

“I’m not going to sink down to a level and argue with people I consider close friends in the press,” Shannon told ET. “That’s not who I am. That’s not what I’m made of.”

“I have a little more decorum than they do,” she added of her former pals’ "lies." "So I don’t want to engage.”
