Rihanna, Gaga and Bieber vie for Billboard awards
After five years of dormancy, the Billboard Music Awards are being revived Sunday with a major dose of star power.
Rihanna and Eminem are among the top competitors, Beyonce is due to receive a top honor, and performers include Britney Spears, the Black Eyed Peas and Cee Lo Green.
The Billboard Awards had been a staple since 1989, but gave out what appeared to be its last award in 2006. This year, the show was brought back.
It's being held in Las Vegas, and will be broadcast live on ABC.
The Billboard Music Awards are given out to music's most popular artists. The finalists and winners are determined by their rank on the Billboard charts and their "social and streaming activity."
