Usher took the headlining slot at day 1 of the iHeartRadio music festival this year, and he made sure to make it a memorable send off. Aside from breaking out plenty of hits from his lengthy back catalog, the R&B legend also brought Chris Brown out to perform a song of his own.
Fresh off the release of X, Chris performed his Usher-assisted single from the effort, "New Flame" which went over pretty well with the crowd.
