Things 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.
