Cooper Flagg’s girlfriend apparently has the power to get under his skin.
The Dallas Mavericks star forward was spotted with girlfriend Arianna Roberson watching a high-profile WNBA meeting between the Indiana Fever and the Dallas Wings at American Airlines Center in Dallas, Texas.
During the game’s broadcast, Roberson was caught on camera turning to Flagg to say something. It was not clear what the Duke Blue Devils center told the Mavs star, but whatever it was, it didn’t seem to amuse Flagg, who rolled his eyes in response.
Here is a clip of that interaction.

While Flagg was not entertained by what Roberson told him, fans online had a great time reacting to the hilarious moment.

Perhaps Flagg found more joy in what he witnessed unfold on the court between the Fever and the Wings, as the Mavericks’ WNBA counterpart took down Caitlin Clark and company, 91-85.
Arike Ogunbowale led the way for the Wings with a 32-point eruption on a 12/22 shooting from the fillr, while Jessica Shepperd scored 26 points on 11/16 shooting.
Dallas’ defense was also successful in keeping Clark in check, with the Fever superstar point guard firing only 10 points on a salty 4/15 shooting.
This is hardly the first time Flagg and Roberson have gone viral together, and it’s safe to assume it won’t be the last.
