Red flag! Shannon Beador has no problem making a scene. The Real Housewives of Orange County star is opening up about her recent altercation with her husband David's ex-mistress, Nicole McMackin.
As Us Weekly exclusively reported, the incident occurred at the USC vs. University of Utah college football game in L.A. on Saturday, Oct. 24.
Beador, 51, tells Entertainment Tonight that she first became upset when she spotted Nicole and her husband, Reed, sitting a few rows behind her. (David and Reed are both USC alumni.)
"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!'" Beador recalled. "I found myself in front of the stands and I yelled, 'This is the woman who had an affair with my husband!'"
She added to ET: "They could buy a seat anywhere."
But it didn't end there. Shannon, who was joined by David at the game, later bumped into Nicole in the tunnel during halftime. An onlooker told Us that Nicole screamed "F—k you!" two inches from Shannon's face.
"Shannon followed with an, ‘Are you kidding me?'" the eyewitness noted. Nicole said that Shannon was sick and crazy, so Shannon quipped back: "Why are you describing yourself to me?"
Following the Saturday incident, Shannon alluded to Nicole in an Instagram post. "Go Trojans! Cheering with good friends! Sorry @tamrajudge couldn't make it!" she captioned an Instagram pic of her loved ones. "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."
As previously reported, David had an eight-month affair with Nicole. Shannon once claimed that his ex-mistress befriended her in order to learn more about the married couple's relationship.
