On Saturday, October 24, Real Housewives of Orange County star Shannon Beador got into a verbal argument with her husband's former mistress, Nicole McMackin, during the University of Utah College football game at the Los Angeles Coliseum.

The 51-year-old Beador recalls the event to Entertainment Tonight saying, "I was shocked to see that she was there, so this time, I'm not going to roll over. I said, 'You have a lot of nerve being here! I found myself in front of the stands and I yelled, 'This is the woman who had an affair with my husband!'"

Shannon Beador reportedly decided to yell up to the section where Nicole was sitting and make sure that everyone knew that this was the woman who had an affair with her husband David Beador.

While David was involved with Nicole, he actually left home for two weeks and even gave their daughter his wedding ring, telling her to give it to Shannon because he didn’t want it anymore.

Shannon did share back in June that they are trying to fix their marriage.

Shannon Beador and her husband David’s affair became public this season on Real Housewives of Orange County when the couple decided to air their issues on the show.

Their intention in doing this was to bring hope to other couples who are going through similar trouble.

David Beador had an 8-month affair with another married woman named Nicole McMackin. According to Shannon, McMackin even befriended her during the affair, which she believes took a lot of courage.

Recently, the American reality television star, said they’ve been doing great and they even went through a grilling interview about the affair from Andy Cohen on Bravo TV.

Beador is currently appearing on the reunion episodes of RHOC, where the issue of David’s cheating is still being addressed.

Shannon later took to Instagram to throw more shade at Nicole. She wrote, "Go Trojans! Cheering with good friends! Sorry @tamrajudge couldn't make it! Someone with no moral compass decided to show up again. Watch reunion part 2 on Monday night and you will understand who I'm talking about. #narcissist #stalker."
