Duke basketball stars Cooper Flagg and Arianna Roberson confirm relationship in 2026

Duke basketball star Cooper Flagg and teammate Arianna Roberson confirmed their relationship after vacation photos and social media posts in 2026.

Duke duo shares vacation moments A TikTok video posted by Duke center Arianna Roberson on Thursday showed her and Dallas Mavericks forward Cooper Flagg during a trip to Turks and Caicos. The clip featured multiple coordinated outfits worn by the pair, with them often seen holding hands in the photos. Flagg also shared a photo of the couple kissing on his Instagram story, accompanied by two black heart emojis, which Roberson reposted on her own profile. ## Rookie award ceremony shared moment During Flagg's Rookie of the Year award presentation last month, Roberson was present at the press conference. She sat among reporters alongside Flagg's parents, Kelly and Ralph. This public appearance highlighted their connection in front of media and fans. ## Duke teammates' overlapping seasons Both Flagg and Roberson played for Duke Blue Devils, though they never shared the court in Durham. Roberson completed her freshman season in 2025-26, averaging 8.0 points and 5.7 rebounds in regular-season games. Flagg, the No. 1 pick in the 2025 NBA draft, played his rookie year with averages of 21.0 points, 6.7 rebounds, and 4.5 assists. ## Flagg's busy offseason schedule Flagg's time away from basketball included serving as the honorary pace car driver for the Würth 400 at Texas Motor Speedway. This event took place before his vacation with Roberson in Turks and Caicos. The young star's offseason activities have kept him in the spotlight beyond the court.
