Kathryn Edwards and her husband, Donnie, may have faced an awkward moment over the weekend.

Have 'RHOBH' Kathryn Edwards & Faye Resnick Ended Their Decades-Long Feud?

After traveling to San Francisco, Calif. for Sunday's Super Bowl, the Real Housewives of Beverly Hills sat in the audience as her former husband, Marcus Allen, was honored as an NFL star.

"Kathryn and her husband Donnie naturally went to the Super Bowl last weekend as Kathryn has expressed her love of traveling (and football players!) while Donnie played in the NFL for over a decade," AllAboutTRH reported on Tuesday. "Also at the Super Bowl this year? Kathryn’s ex-husband Marcus Allen who was the cause of the Faye Resnick/book drama that has caused some much tension between the two this season!"

In Resnick's book, the longtime friend of Kyle Richards alleged Edwards' ex-husband, Allen, who was a friend of O.J. Simpson years ago, engaged in an affair with Nicole Brown Simpson while he was engaged, and later married, to Edwards.

"Football hall of famer (and Kathryn's ex) Marcus Allen was one of the past Super Bowl MVP's honored before this year's 'Super Bowl 50' game and had his name announced and proudly walked out on the field," the site explained.
