Shannon Beador has no regrets about ending her friendship with Vicki Gunvalson.

“The bottom line is, this entire season … I don't have a problem with her being in the same room,” Shannon says. “I'm fine with her. I can sit there and have a drink, whatever. And you will see that we start to have a lot more fun together, and then the season culminates with me saying, 'I made a really good decision with backing off from this friendship.'”

The onetime besties fell out during season 10 of The Real Housewives of Orange County, which centered around Vicki and her now ex-boyfriend, Brooks Ayers, possibly lying about his cancer diagnosis.

“Shannon and I are not in a good place,” Vicki told ET just before season 11 premiered. “I'm OK with it. We had a great time in Ireland, which you're going to see, and then it turned again.”

The ladies head to the U.K. in future episodes this season for their annual cast trip.

“There's just things that happen that you just scratch your head at and say, 'Why?'” Shannon teases.

“We were all having a great time until Kelly [Dodd] got mad and she told us all the horrible things [Vicki] was saying about us,” Tamra Judge previously revealed.

“That is absolutely correct,” Shannon says. “Absolutely correct.”

Watch the drama unfold every Monday night on Bravo at 9 p.m. ET, when new episodes of The Real Housewives of Orange County air. In the meantime, check out more of our chat with Shannon below.
