Trouble in paradise?

Just days after Cardi B and Stefon Diggs surprised fans by reuniting at the NFL star’s Mother’s Day event, the pair were caught having a tense argument outside of a coffee shop and a gym in Burtonsville, Maryland, on Wednesday.

In a video shared online, the “Up” hitmaker, 33, could be seen looking pretty animated as she yelled at Diggs, who took Cardi’s aggression with a relaxed demeanor.

The athlete, 32, leaned back against a car with his arms folded as the rapper approached him.

It’s unclear as to what the couple was arguing about — however, it’s clear that the topic was pretty serious considering Cardi’s behavior. At one point, a man with Cardi could be seen in the clip putting his hand on her shoulder in an attempt to calm her down.

TMZ was first to report the news.

A source told the outlet that Cardi was overheard saying “that bitch is messy” at Diggs during the showdown — which lasted about 10 minutes, per sources.

Reps for Cardi and Diggs did not immediately respond to Page Six’s requests for comment.

As we previously reported, the exes — who welcomed a son together last November — packed on the PDA over the weekend when Cardi made a surprise appearance at the former Patriots player’s Diggs Deep Foundation Mother’s Day wellness event on Saturday.

Video shared online by sports journalist Kelsey Nicole Nelson showed Diggs kissing the Grammy winner on the cheek and affectionately wrapping his arm around her waist while posing for photos.

Soon after, a source told Us Weekly that Cardi is giving Diggs “a second chance but is not fully committing to him.”

The two stars reportedly called it quits in February — nearly a year after they went public with their relationship — as Diggs and his New England Patriots prepared to face off against the Seattle Seahawks in the 2026 Super Bowl.

At the time, it was reported that the pair had unfollowed each other on Instagram, with a source telling People that Cardi “couldn’t trust” Diggs.
