Eminem, Justin Beiber Dominate Billboard Music Awards [PHOTOS] [VIDEOS]

Detroit rapper Eminem and pop sensation Justin Bieber showed up the rest of the music world at last night's Billboard Music Awards. Each of them took home an impressive 6 awards.

Second place in the awards tally was a bit more crowded with 6 artists that won 3 trophies apiece; Rihanna, Lady Gaga, Usher, Taylor Swift, Mumford & Sons and Taio Cruz.

Read more for photos of most of this year's winners, and videos of some of last night live performances.

Rihanna & Britney Spears make everyone feel a little dirty with their performance of "S&M" and "till The World Ends".

OneRepublic, Far East Movement, and Snoop Dog??? Epic.

Beyonce struts her stuff performing her new song "Who Run The World (Girls)".  It's a pretty epic performance, but (I think) a terribly annoying song.

It looks like Ke$ha was trying to channel her inner-Gaga with her performance of "Blow".

Taio Cruz lights up the Billboard stage with "Break Your Heart" and "Dynamite".

Cee Lo Green performes a medley of hits, and does most of it while suspended in mid air with a glittery piano.

Britney comes out for another collaboration with Nicki Minaj. Minaj is a strange woman, very strange.
