Eugenie was the picture of concentration as she watched the game unfold. With her hands clasped in front of her face, she soaked up the atmosphere as she enjoyed her first American basketball experience.
Eugenie, who was dressed all in black, was sat alongside Gossip Girl actress Michelle Tractenberg for the NBA game. Supermodel Christie Brinkley was also in the crowd.
The 23-year-old granddaughter of the Queen is now almost three months into her new job at online auction house Paddle8 in Manhattan.
Based in a stylish apartment in the trendy Meatpacking district, Eugenie is said to be "making the most" of her time in New York.
She is no doubt missing her friends and family though, especially boyfriend Jack Brooksbank, who visited Eugenie in October.
Despite the 3,500 miles between them, the couple's relationship is going from strength-to-strength.
"We spend a lot of time on Skype," Jack, 27, told the Mail. "It's great. We are still very much together."
Eugenie could soon be back in Britain though. Her boss Alexander Gilkes has said that Paddle8 is set to open an office in London.
"We've got a guy over here right now building a team," he told the Telegraph at the GQ 25th anniversary dinner in Westminster last month.
"We're opening an office in London at the beginning of next year. One of our investors is Damien Hirst and his businessman is helping us.
"Jay Jopling is another investor who is offering us extra office support when we need it."
Eugenie has a degree in Art History and English Literature from Newcastle University.
