(Radio.com) Usher's good friend Nick Arison recently tied the knot with Jenna Green and invited another buddy, American Idol alum Brandon Rogers to join in the fun.

The talented twosome didn't miss the opportunity to perform Usher's hit "Yeah" before the giddy crowd. And with the help of manager and best man Scooter Braun, Usher was coaxed to take the stage, reported Billboard.

"It was sort of impromptu," Rogers said. "[Justin Bieber manager] Scooter Braun came up to the stage and asked us for an Usher song, and we called him out!"

Rogers has contributed backing vocals to Usher in the past. See the pair celebrate here.
