"I was shocked to see that she was there, so this time, I'm not going to roll over," The Real Housewives of Orange County star shared. "I said, 'You have a lot of nerve being here!'"
Both Shannon and Nicole's husbands are USC alumni, and through "an unfortunate coincidence," according to an eyewitness, the two couples were seated only about 15 rows apart.
"I found myself in front of the stands and I yelled, 'This is the woman who had an affair with my husband!'" Shannon recalled.
Their confrontation was preceded by an encounter in the tunnel during halftime, during which Shannon said to Nicole, "You have a lot of nerve being here Nicole." Nicole then got in Shannon's face and said, "F**k you, you are crazy."
Shannon also posted on Instagram about the encounter, writing, "Someone with no moral compass decided to show up again."
While Shannon admitted that it's normal for Nicole and her husband, Reed, to attend home games, she seems most upset by their proximity to her family. "They could buy a seat anywhere," she said.
During the football game confrontation, Shannon reportedly yelled at Nicole, "Wait until Monday. Wait until Monday. The press will be all over you again -- you just wait."
