He may have lost out on winning an American Music Award this year, but at least Justin Bieber had gorgeous girlfriend Selena Gomez on hand to comfort him!

Presented by his friend and collaborator, Sean Kingston, the "Baby" singer took to the stage to perform his festive hit single "Mistletoe," from the chart-topping Christmas album, "Under the Mistletoe", while wearing an all-white leather motorcycle outfit.

Justin also helped close down the awards show with LMFAO, as they performed their hit “Party Rock Anthem” while showing off some killer dance moves.

You're still a winner in our eyes, JB
