'RHOC' Shannon Beador Reportedly Screamed at Husband's Ex-Mistress During USC Football Game

The Real Housewives of Orange County's Shannon Beador can't seem to escape her husband's past infidelities. According to a recent Entertainment Tonight report, Beador was reportedly seen screaming at her husband's ex-mistress during a University of Southern California football game on Saturday (Oct. 24).

Allowing a cheating partner back into your life can be challenging, but what happens when you're constantly haunted by their mistakes? Beador reportedly got into a verbal altercation with Nicole McMackin, her husband David's former side piece. The incident took place at the Los Angeles Memorial Coliseum as USC went head-to-head against the University of Utah, an eyewitness told ET.

The eyewitness recalled seeing Shannon yelling while the two teams were warming up on the field. As soon as the second half of the game kicked off, an argument erupted when Nicole and a group of friends were walking through a coliseum tunnel heading back to their seats. Shannon was reportedly standing at the side of the tunnel cursing and yelling at them.

Both Shannon and Nicole's husbands are USC alumni who are often spotted attending the Trojan games. In a turn of bad luck, Nicole and her husband, who serve as season ticket holders, were apparently seated just 15 rows in front of where Shannon and David were sitting.

"Shannon, go sit down. No money to be made here. Please let us be," Nicole's husband reportedly jumped in to say. Someone from Nicole's entourage then began shouting back at Shannon, threatening to call security if she didn't leave them alone.

Shannon grabbed Nicole's arm and Nicole released herself from Shannon's grip by swinging her arm back. Shannon warned Nicole to "wait until Monday" because the press would be covering the entire ordeal. She was referencing the RHOC reunion show airing on Monday (Oct. 26) on Bravo.

Unfortunately, the ugly comments didn't stop there. "That's Nicole McMackin. She slept with my husband about three to four times," Shannon shouted at Nicole and her friends later in the game as they were walking down the stairs.

David's affair played a major role in the most recent season of RHOC. In an episode that aired in June, it was revealed David carried on an affair with Nicole for eight months and there was a two-week period where he actually left her.

The Beadors are currently working to repair their marriage and are looking to one day move on from the incident, Shannon told ET.
