Fans witnessed Bieber spontaneously serenading Gomez at the "empty" hotel bar, launching into heartfelt renditions of the '60s classic "My Girl" and his new single "Sorry."
After the warm performance, Gomez took a photo of several fans with Bieber (check out his expression to see how he smiles when the photographer is "his girl") and then asked to join them at their table to chat.

Are Justin and Selena an item again? It's hard to say with these two, but Gomez told Elle in February that she couldn't completely discount the idea of getting back together with her first love someday.
