Now, fans are paying equal attention to his life away from basketball after Arianna Roberson publicly confirmed their relationship online.

Cooper Flagg And Arianna Roberson's Duke Basketball Connection Draws Attention

Cooper Flagg and Arianna Roberson both arrived at Duke during the 2024-25 season, though their journeys looked very different at the beginning. Flagg became college basketball's biggest name after winning the Naismith Player of the Year award, while Roberson's freshman season was paused because of a knee injury. Even then, Duke fans often noticed the two around campus and slowly started connecting the dots.

The first major rumors appeared when Roberson was seen attending Duke's game against Syracuse alongside people close to Flagg. Later, fans became even more convinced during Flagg's Rookie of the Year celebration when Roberson sat courtside beside his parents. Neither of them addressed the speculation publicly at the time, but social media conversations continued growing throughout the season.

Arianna Roberson already had a strong basketball reputation before the relationship news became public. The San Antonio native was a McDonald's All-American at Clark High School and joined Duke as a five-star recruit. She also represented Team USA in both the FIBA U18 AmeriCup and FIBA 3x3 U18 World Cup in 2024, helping the team win gold medals. Her comeback season with Duke later added another important chapter to her growing career.
