Paul Drinkwater/Bravo/NBCU Photo BankThings got heated at a University of Southern California football game on Saturday, but it wasn't between the players on the field…
Real Housewives of Orange County star Shannon Beador got into a verbal altercation with her husband's former mistress, Nicole McMackin, while USC played Utah at the Los Angeles Coliseum.
Both Shannon and Nicole's husbands are USC alumni, and an eyewitness tells Entertainment Tonight that the two couples were seated just a few rows away from one another.
The witness says Shannon began yelling during warm-ups. Then, at the beginning of the second half, Nicole and her friends were heading back toward their seats when Shannon began yelling and swearing at her again.
Nicole's husband jumped in, saying, "Shannon, go sit down. No money to be made here. Please let us be," according the bystander. One of Nicole's friends then started threatening Shannon they were going to call security.
Shannon responded by grabbing Nicole's arm, which she flung away to release herself.
"Wait until Monday. Wait until Monday. The press will be all over you again—you just wait," Shannon started screaming, referencing the RHOC reunion show that airs tonight on Bravo.
At the end of the game, Shannon started in again when Nicole walked down the stairs past her. The source says she began jumping up and down and yelling, "That's Nicole McMackin. She slept with my husband about three to four times." David reportedly sat in silence with his head down and embarrassed.
But it didn't end there.
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."
The cheating scandal first came to light on an episode of RHOC in June during which it was revealed that David had been having an eight month affair with Nicole and even left Shannon for two weeks because of it.
Both Shannon and David explained that the situation was much more painful than people even realize. "I don't think people understand the level of hurt," and the blond star explained on an episode of Watch What Happens Live earlier this month.
"One day he handed [our daughter] Stella his wedding ring and said, 'Give this to your mother, I don't want it anymore,' and that was a knife in my heart," she said.
"I thought we're never going to get back together and I had to do some of the interview commentary for the show and I wore his wedding ring because there wasn't any way I was going to give up."
However, it appears the couple is going strong again. Shannon took to Instagram Saturday night to share a sweet photo kissing her husband's cheek and writing, "Love my husband! Having an amazing night at the most incredible restaurant @panxacocina #restored #godisgood."
Meanwhile, Nicole and her husband have also reportedly repaired their marriage and are simply looking to move forward from the scandal.
