Justin Bieber Performs Medley in the Rain at 2015 American Music Awards [VIDEO]

Justin Bieber closed out the 2015 American Music Awards Sunday night (Nov. 22) with an epic performance of his top three songs this year: "What Do You Mean," "Where R U Now" and "Sorry."

In a long white hoodie and a trucker hat, the Canadian crooner grabbed his mic to sing "What Do You Mean," off of his latest album, Purpose.

Nearly each member in the crowd had glowing sticks swaying side to side to the love ode. As he geared up for the next track, he hyped up the crowd by asking "AMAs, What's up?" Naturally his words were met by screams from the Beliebers.

"I gave you the key when the door wasn't open," he began singing on the next song, "Where R U Now." With choreography that included tutting, some foot work and the whip, Bieber proved he's still got solid moves.

Then rain fell from the sky. Yes, water actually dropped down from the top of the stage as the "Baby" singer started his final performance of the night with "Sorry." He kicked and splashed around in the water as it fell over his head, drenching his hoodie. His dancers got in on the sloshing around as well.

While the announcer called the performance a "game-changing" finale, his fans on Twitter seemed torn on the magnitude of how great it was. Some cited that the Biebs was lip syncing while others believe he's "killin the game."
