When Prince Harry was living in the United Kingdom, it wasn’t uncommon to see him quietly slip into the stands of a British rugby game or two each season. It seems the same can now be said about the Duke of Sussex and America’s national sport.

Harry attended last night’s Super Bowl alongside Princess Eugenie, who is visiting California with husband Jack Brooksbank and son August Philip Hawke Brooksbank, who turned one last week.

The cousins kept a low profile in black face masks as they took their seats in the 70,000-seat SoFi Stadium in Inglewood on February 13 to watch the Los Angeles Rams take on the Cincinnati Bengals in the 56th final of the NFL playoffs.

During the game’s halftime show, Harry and Eugenie were spotted by onlookers dancing in their seats to hip-hop and R&B anthems from Eminem, Dr. Dre, Snoop Dogg, 50 Cent, and Mary J. Blige—songs that would have no doubt been a reminder of their days partying together in London.

While it’s easy to imagine many brands vying to host the Duke of Sussex, he watched the game in a suite sponsored by Salesforce, one of the official partners of BetterUp, the mental health and coaching platform where he’s currently chief impact officer. The company was also an advertiser during the game, premiering a commercial starring Matthew McConaughey to encourage consumers and corporate giants to think about their value systems.

The night, which saw the Rams win 23-20 over the Bengals, was a rare public outing for the close friends, who left their other halves, Duchess Meghan and Jack Brooksbank, at home for the evening. (Reps for both royals refused to comment on which teams they were cheering for.)

Backstage, Harry even spent time making a few new friends in one of the many VIP areas at the stadium. Country music artist Mickey Guyton, who gave a stirring rendition of the national anthem before kickoff, shared on Twitter that she had a very casual encounter with the duke. “He was just lovely,” she wrote. “I even curtsied in my track suit.”

Other celebrities in attendance included Jennifer Lopez, Ben Affleck, Drake, Ellen DeGeneres, Portia de Rossi, Justin Bieber, Hailey Bieber, Kendall Jenner, Jay-Z, and Blue Ivy Carter.

Harry is no stranger to football. During a 2013 visit to the U.S. Air Force Training Academy in Colorado Springs, the prince joined a training session with cadets to help raise awareness for the Warrior Games. Troy Calhoun, head football coach at the time, was impressed with Harry’s quarterback abilities. “He is aggressive, he is strong, he is smart, I would love to sign him up to the Air Force Academy football team if I could,” he said. “Honestly, I was a little surprised how good he was!”
