Paul Drinkwater/BravoThe Real Housewives of Orange County season 10 is coming to a close and it's safe to say some relationships will never be the same. Former gal pals Vicki Gunvalson and Shannon Beador seem to be closing out the season on opposite sides of the friendship fence, as you can see in the exclusive clip below.
Everybody has been harping on Vicki and her (then) boyfriend Brooks Ayers about whether or not he actually has cancer. In the process a rift formed between Viciki and Shannon—and that rift widened exponentially at Tamra Judge's baptism when Vicki's brother's girlfriend confronts Shannon about David Beador's affair.
"She's going to go beat somebody's ass," RHOC's Lizzie said as Shannon marched toward Vicki.
"Thank you so much, for being the true friend and not telling anybody my secrets," Shannon said as she clenched Vicki's arm.
"What secrets?" Vicki asked. "What just happened?"
Oh yeah, the affair.
"It wasn't like I was telling a secret," Vicki said in a confessional. "Shannon had already told Tamra and Heather. I was just telling Rhonda and Billy what they were going through because Billy knows David and Shannon because we were in Mexico together."
Rhonda brought up the affair because of all the talk about Brooks' cancer battle.
"I'm just gonna say, 'Shannon vs. Vicki.' That pretty much describes the finale to me," Shannon told us in September. "And it's not something that I'm excited about. It's not something that should've happened."
