According to Us Weekly, Real Housewives of Orange County star Shannon Beador got into a public confrontation with someone we’re sure she hoped never to see again: her husband’s ex-mistress, Nicole McMackin.

Eyewitnesses told the magazine that the spat happened at a University of Southern California football game Saturday in Los Angeles, where Beador reportedly noticed McMackin was in attendance and initially tried to ignore her.

But eyewitnesses said McMackin was purposefully trying to grab the attention of Beador and her husband by walking right by them, and eventually, Beador was returning to her seat when she ran into McMackin in the tunnel.

“That’s when Shannon calmly said to Nicole, ‘You have a lot of nerve being here,'” the insider said, adding that McMackin responded by putting her face “two inches from Shannon’s face” and screaming, “F*** you!”

The witness continued, “Shannon followed with an, ‘Are you kidding me?’ to which Nicole replied, ‘You’re sick and you’re crazy.’ Shannon responded with, ‘Why are you describing yourself to me?'”

Beador reportedly then yelled up to the section where McMackin was seated to watch the game, “Nicole is the woman who had an affair with my husband!” The eyewitness told Us Weekly that McMackin seemed unfazed by the encounter.

Beador and her husband spoke to Andy Cohen on Watch What Happens Live earlier this month, opening up about the affair and its effect on their marriage.

“I don’t think that people understand the level of hurt,” Beador explained. “I’m just gonna give an example, OK? When [my husband] David left me for those two weeks, he would still come and pick the kids up from school. And one day he handed [our daughter] Stella his wedding ring. He said, ‘Give this to your mother. I don’t want it anymore.'”
