Tamra Barney Dishes On Vicki Gunvalson & Brooks Ayers' Split

After sharing a photo of herself and Meghan King Edmonds, the Real Housewives of Orange County star faced allegations of being a "snake."

"Cheers from St Louis with @meghankedmonds," Barney wrote on Instagram on Thursday. "Just saw the Edmonds home @jpe1515. I love it here."

In addition to simple comments, including "Dislike" and "Oh, Lord," fans slammed Barney for betraying her longtime friend, Vicki Gunvalson.

"If it [wasn't] for Vicki embracing you YEARS ago and your resulting friendship with her, you would not be the draw that you are," one fan alleged. "You repay that with phony friendship and laughable loyalty. This photo is yet again proof that you are nothing but a snake... Of course you'd befriend a person who is a scathing POS toward your long time friend."

"Where is your friendship loyalty to Shannon and Vicki? Or do you need a dictionary to look up the definition of the word?" another woman asked.

A third fan pointed out that Barney's friendship with Edmonds may be nothing more than a business move.

"Remember she wants Meghan to buy real estate from her," the fan noted. "It's all a business move.. I must say a smart sales approach... May not be a truly loyal friend but she's definitely a smart business woman."
