It seems like the self-proclaimed "Tres Amigas" are no more.

Fans of Bravo's "The Real Housewives of Orange County" watched as the threesome that consisted of Shannon Beador, 56, Tamra Judge, 52, and Vicki Gunvalson,58, bonded and subsequently dubbed themselves the "Tres Amigas" over the last few seasons. But, like life, things can change in an instant and the trio appears to be no longer.

What happened? The catalyst that seemingly marked the end of their deep friendship was when Tamra and Vicki announced that they would not be a part of "RHOC" Season 15.

"Shannon and Tamra used to talk every single day," an insider revealed to AllAboutTheTea.com. "After Tamra left the show, the phone calls dropped drastically. Shannon doesn’t even answer Tamra’s calls anymore — and does not return her texts."

"She treats Vicki the same way," they added.

Tamra and Vicki, within days of each other, revealed in January that they would not be participating in the upcoming season. Their departure from the series that started the entire "Housewives" franchise doesn't mean fans won't be able to see them on their screens any longer.

The longtime pals, who have a rollercoaster of a friendship, have teased that they already have something new in the works. In an Instagram photo from early March, the former "RHOC" stars appear to be enjoying a glass of wine together and chatting while sitting at a kitchen counter -- a pretty normal sight for the ladies. However, in the left corner of the photo, a cameraman can be seen filming them.

"How’s your Sunday?" Tamra captioned the photo, along with the hashtag #lifeafterhousewives.

Meanwhile, the OG of the OC wrote, "Just another Sunday night," followed by the hashtags #lifeafterhousewives #cantkeepusdown and #woohoo.

"It’s going to be an incredible show," the mother of two dished a few days later. "Tamra and I, we’re good together. We have great chemistry and we’re having fun. We’ve got a really special journey happening. It’s something that will really inspire people. I can’t say much more, but I know it’s going to be a show people love."
