'RHOC' Drama! Shannon Ends Friendship With Tamra After Another Blowout Fight

With friends like Tamra Judge, who needs enemies?

After last week's shocking episode — which exposed Judge, 51, starting the nasty fight between Shannon Beador, 54, and The Real Housewives of Orange County cast — RadarOnline.com has exclusively learned Beador feels "betrayed" by her BFF — and is cutting her ties once and for all!

During last Monday's shocking episode, Gina Kirschenheiter, 34, and Kelly Dodd, 43, revealed to Beador that Judge had the entire cast concerned for her mental health and would not shut up about it.

Beador then called Judge, who put the blame on Kirschenheiter. Beador believed Judge — until the episode proved Judge was the one to start all the drama!

"Shannon and Tamra are so codependent on each other and Tamra knows that she really f****d up this time," and RHOC insider said, adding that there was "no denying what Tamra did wrong."

Since their falling out last week, Beador — who has also been accused of being "jealous" of Judge — has been posting a ton of photos on her social media with her gaggle of gal pals. Noticeably absent from Judge's blonde ambition tour, however, is Judge!
