One of the most noteworthy events at last night's Billboard Music Awards had nothing to with the music itself -- it was the kiss Justin Bieber and Selena Gomez shared when Bieber was announced as the Top New Artist of the year.

Interestingly, when Bieber won his first award of the evening, for Digital Artist of the Year, he appeared to lean in for a kiss, but Gomez had turned away, so he instead gave her a peck on the forehead.

Perhaps they had a conversation about that afterwards. Because when the Far East Movement told the world Bieber was Billboard's Top New Artist, the teen power couple popped up in unison and locked lips for the cameras.

We can only imagine how the young Bieber fans who were mad that their hero had a girlfriend must be feeling now that Justin and Selena are engaging in public displays of affection. But most of the world can appreciate young love, and these two sure seem to be happy together at the moment!
