Fresh off his Rookie of the Year award, Dallas Mavericks Cooper Flagg made things Instagram official with girlfriend, Duke women’s basketball center Ari Roberson, on Thursday.
Flagg, who led Duke to the Final Four last March before Dallas took him first overall in the 2025 NBA Draft, shared a snapshot of the pair kissing while in Turks and Caicos on his Instagram Story.
Roberson, a 6-foot-4 redshirt freshman for the Blue Devils, reposted the photo with two black heart emojis.
She also shared a TikTok video that showed them doing an online trend, which included moments from their vacation.
“Carry on…” she wrote with a kissing face emoji.
Roberson is the younger sister of former Oklahoma City Thunder forward Andre Roberson, who last played with the Nets in 2020-21 after six seasons with the Thunder.
Flagg and Roberson made waves online when they shared individual photos of themselves enjoying the same swings over the ocean at Noah’s Ark in Turks and Caicos last Friday.
Before that, Flagg and Roberson stirred buzz when they attended Duke’s 101-64 blowout win over Syracuse at Cameron Indoor Stadium in February.
They seemingly met through their Duke connection.
Roberson overlapped with Flagg for a year at the school when they were freshmen in the 2024-25 season.
Their vacation comes on the heels of Flagg winning NBA Rookie of the Year and edging his former Duke roommate Kon Knueppel, currently a Charlotte Hornets forward, for the honor.
The 19-year-old Flagg became the second-youngest player to win the award behind Lakers superstar LeBron James.
This past year, Roberson averaged 8.0 points per game on 41 percent shooting across 33 games for the Blue Devils.
