Usher, Outkast Clean Up At World Music Awards

Artists each take home three awards; Norah Jones wins a pair.

First the U.S., then the world: Usher and Outkast, who received the most nominations for the upcoming American Music Awards, were crowned the world's best at Wednesday night's World Music Awards.

The artists each took home three awards — Usher won for World's Best Male Artist, Best R&B Artist and Best Pop Male Artist, while Outkast were honored with awards for World's Best Group, Best Pop Group and Best Pop/ Hip-Hop Artist.

Norah Jones trailed closely behind the R&B and hip-hop stars with a pair of trophies for World's Best Female Artist and Best Pop Female Artist.

Single honors went to Avril Lavigne (Best Pop/ Rock Artist), Evanescence (Best Rock Artist), Alicia Keys (Best R&B Female Artist), Hilary Duff (Best New Female Artist), Kanye West (Best New Male Artist) and Maroon 5 (Best New Group).

Music mogul Clive Davis was handed the Outstanding Contribution to the Music Industry Award while Dido was crowned the U.K.'s Best-Selling Artist.

The ceremony, which honors the world's best-selling recording artists (as opposed to "world music," a record-store term for music from cultures other than those of Western Europe and North America), took place in the United States for the first time, in Las Vegas, after formerly being held in Monaco. The awards were broadcast live in the U.S. and will later be screened in more than 150 countries.
