Cooper Flagg has hard-launched his relationship with Arianna Roberson.
Flagg posted a photo of the couple kissing on his Instagram story Thursday with two black heart emojis. Roberson reshared the same post to her story and also posted a TikTok of her and Flagg showing off multiple outfits from their trip to Turks and Caicos.
Roberson was a freshman at Duke the same season as Flagg, but she didn’t play in 2024-25 because of an injury.
Flagg isn’t Roberson’s only tie to the NBA. She’s the younger sister of former NBA guard Andrew Roberson, who played seven seasons in the NBA from 2013-21, mostly with the Oklahoma City Thunder.
Roberson, a San Antonio native, led Clark High School to its first-ever girls basketball state title in 2023.
