Usher and Chris Brown looked like old pals onstage in Atlanta this week. Behind the curtain, things are still a lot more complicated.

Video taken Tuesday at Mercedes-Benz Stadium captures the pair slapping hands before they pull each other in for an embrace. The moment came as they closed out the fourth of five nights in the city.

They kept the good vibes going for the crowd throughout the set.

A shout-out Usher didn't see coming

During that same show, Chris praised Usher and called him his "brother." Insiders say Usher had no idea that was coming.

Offstage, the two still have not sat down to talk since their blowup last week. Sources say Usher has relatives traveling with him, which has made it tough to find time alone with Chris.

Teams step in

Their camps met this week without either singer in the room. The goal was to come up with a plan to get the two back in sync.

Both sides agreed the attitudes have to go. They also agreed the men need to talk as soon as possible since more tour dates are still ahead.

How the feud started

The trouble began at their first Atlanta show. The singers reportedly got into a heated fight backstage that held up the concert for a long time. Insiders blamed egos.

As recently as Tuesday, the relationship was being described as "still icy."

About those canceled shows

The pair also scrapped a Los Angeles date and a Miami date. Both were extra shows added to the schedule. They still have other concerts booked in both cities.

Insiders say the cancellations had nothing to do with the feud. The real issue was weaker ticket sales than expected.

One more Atlanta show is set for Wednesday night. The crew is reportedly pumped for it, with as many as six surprise guests possibly joining them.
