Usher didn't need any "Confessions" to prove he's the world's best male artist. The singer earned three 2004 World Music Awards on Wednesday, while Outkast — the big winner at this year's Grammys— also took home three awards.  

Buxom actress Pamela Anderson wore a tight, black miniskirt to present Usher with his first award and joked with the audience about searching for a boyfriend.

"So, Pamela, I don't mean to start any rumors, but I'm single," Usher told the former "Baywatch" star.

For the first time, the awards show was broadcast from the United States after previously being held in Monaco.

The two-hour show honoring the world's best-selling recording artists was broadcast live on ABC throughout the United States, Mexico and Canada from the Thomas & Mack Center at the University of Nevada, Las Vegas.

An additional hour filled with awards and performances by international artists was taped for a later worldwide broadcast to more than 150 countries.

Besides world's best male artist, Usher was honored as best pop male artist and best R&B artist. His latest album, "Confessions," has sold more than 5 million copies.

Outkast won for world's best group, best pop group and best rap/hip-hop artist. Norah Jones also was a big winner, winning awards for world's best female artist and best pop female artist.
