Dallas Mavericks forward Cooper Flagg recently updated the public on his personal life through his official channels. The announcement confirms long-standing rumors about his connection to another top athlete.
Flagg and Duke women’s basketball star Arianna Roberson have officially confirmed their relationship on social media. This big confirmation follows weeks of continuous romance rumors surrounding the 2026 NBA Rookie of the Year and the current Blue Devils center.
The exciting romance rumors initially sparked back in April 2026 when Roberson attended Flagg’s major NBA Rookie of the Year press conference and sat directly alongside his supportive family.
In early May 2026, the two basketball players fueled heavy speculation by posting separate, nearly identical photos from Noah’s Ark Beach Club in Turks and Caicos on the very same day.
On May 15, 2026, Roberson published a viral vacation TikTok video featuring the young couple trying on different outfits together. Concurrently, the Dallas Mavericks star forward posted a sweet Instagram story showing the two sharing a kiss, with a nice black heart emoji.
Roberson is a talented 6-foot-4 center for the Duke Blue Devils women’s basketball team. She first crossed paths with Flagg when both players were freshmen at Duke University during the 2024–25 college academic year.
After redshirting her true freshman season due to an unfortunate injury, she averaged 8.0 points and 5.7 rebounds per game in her first active season, helping lead the Duke team to the Elite Eight tournament.
Roberson is also the younger sister of seven-year NBA veteran Andre Roberson, who previously earned NBA All-Defensive Second Team honors with the Oklahoma City Thunder team during his professional career.
