The Billboard Music Awards took Las Vegas by storm on Sunday (May 20), as Adele, LMFAO, Justin Bieber, Katy Perry and Taylor Swift came away top prizes.

British Grammy-winning singer Adele won 12 awards from 18 nominations for her juggernaut album "21," including top artist, top female artist and top album. Her awards were not presented during the live show and the singer was not present.

R&B singer Chris Brown took honors for top new artist, male artist of the year and R&B artist of the year, respectively.

Bieber picked up the award for the most social artist, thanking his 22 million Twitter followers and 43 million Facebook fans, saying "the Internet is where I got my start."

Perry was given the Spotlight award for being the only female artist in history to see five No. 1 singles from one album. Michael Jackson is the only artist to have received the award previously.

SOUNDBITE Katy Perry saying (English):

"They told me the only other person that received this award is Michael Jackson, so I feel incredibly honored to be in that same category, although I don't compare at all."

Taylor Swift was given the Woman of the Year prize. The country/pop artist is already an industry veteran at 22, having won all the top awards in music, including six Grammys.
