After winning the award for Top New Artist at the Billboard Music Awards Sunday in Las Vegas, Justin Bieber gave his girlfriend, singer and actress Selena Gomez, a very public kiss. The much-hyped kiss has nearly overshadowed the awards show itself in the hours after it ended.

The two have been dating for several months. Soon after the new year, Billboard reported Bieber and Gomez were seen kissing in the Caribbean while on vacation.

In addition to Top New Artist, Bieber won Digital Artist of the Year, Top Social Artist, Top Streaming Song (Video) for "Baby" featuring Ludacris and Top Pop Album for "My World 2.0."
