LOS ANGELES, Oct. 26 (UPI) -- Shannon Beador reportedly had a run-in with her husband's former mistress, Nicole McMackin at a football game.
An eyewitness told Entertainment Tonight the 51-year-old Real Housewives of Orange County star and husband David Beador were at a University of Southern California football game when Shannon Beador confronted McMackin after halftime.
The reality star allegedly had words with her husband's ex-lover before yelling, "That's Nicole McMackin. She slept with my husband about three to four times!" A different bystander told Us Weekly Shannon Beador initially ignored McMackin, who was trying to catch her attention in the first half.
"Go Trojans!" the star captioned a photo of herself with David Beador and friends at the game. "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."
Shannon Beador first revealed her husband was unfaithful on The Real Housewives of Orange County season 10 premiere in June, and later blamed her appearance for his infidelity in an interview with People. David Beador and McMackin had an eight-month affair in 2014.
Beador and her husband have been married 14 years, and share daughter Sophie and twin daughters Stella and Adeline. The reality star will appear on part 2 of The Real Housewives of Orange County season 10 finale Monday at 9 p.m. ET on Bravo.
