Is there something in the water?

Usher and Chris Brown canceled two of their upcoming tour stops after rumors that the singers were feuding surfaced.

People who were planning to attend the R&B Tour on Nov. 16 at SoFi Stadium in Inglewood, California, and on Dec. 6 at the Hard Rock Stadium in Miami received cancellation emails from Ticketmaster.

Fans were told they would be refunded to the “original method of payment.”

However, the “New Flame” collaborators still have scheduled shows at SoFi Stadium on Nov. 15 and at the Hard Rock Stadium on Dec. 3 and 5.

Page Six has reached out to Ticketmaster as well as Usher and Brown’s reps for comment but did not immediately hear back.

While the reason for the cancellations is not publicly known, it comes after rumors that drama has been brewing behind the scenes between Brown and Usher.

On Nov. 5, the “Yeah!” crooner, 48, and the “Loyal” singer, 37, kicked off the first of five shows at the Mercedes-Benz Stadium in Atlanta.

However, concertgoers were shocked when the shows started more than two hours late and ended without the experience they paid for — with Brown and Usher not performing together as they’ve done at their previous concerts.

The show kicked off with the duo’s hit “Party,” however, only Brown graced the stage for his portion of the performance, while Usher never showed up for his part.

When Usher did hit the stage, he told the crowd, “Welcome to MY show.”

Fans also complained that the show ended early and that both musicians did not take the stage together to close out with their 2014 hit, “New Flame.”

TMZ reported that the “This Christmas” actor and the former “Voice” coach got into a verbal altercation backstage before their Nov. 5 show in ATL.

Sources told the outlet that Usher wanted to start the show, while Brown wanted to wait for more fans to arrive, as they were stuck in traffic around the stadium.

The insider said the Grammy winners — who have reportedly been extremely competitive the entire tour — “went back and forth” and the tension reached a head due to “egos.”

Brown took to his Instagram Stories to deny the reports, writing, “Internet 🧢. Don’t fall for it.”

The R&B Tour concludes on Dec. 12 in Tampa, Florida.
