Barack and Michelle Obama joined the likes of tennis great Billie Jean King, fashion designer Anna Wintour and US ski icon Lindsey Vonn in watching Gauff progress into the next round.
Many of the stars were in town to celebrate the 50th anniversary of equal pay at the US Open, with a ceremony taking place on court.
“I actually just met [the Obamas] right before I came in here,” Gauff told reporters after her win, according to the WTA.
