Some of the biggest acts on the charts will be on hand to take the stage when the 2011 Billboard Music Awards hit Las Vegas on May 22. Rihanna, Jennifer Lopez, the Black Eyed Peas, Taio Cruz, Keith Urban and 2010's crossover kings, Lady Antebellum, have all been tapped to perform at the show, which ABC will air live from Sin City's MGM Grand.

The event honors artists who have appeared on the Billboard charts during the period of February 28, 2010, through March 1, 2011. Winners are also determined by album, single and digital sales, touring, streaming and social interactions on MySpace, Facebook and other popular online destinations for music, according to Billboard.com.

"This show marks the first of several broadcast platforms we plan to build around the Billboard franchise," Richard D. Beckman, CEO of Prometheus Global Media, which owns the magazine, said in February about the show. "We have an incredible network partner and with Don Mischer, one of the finest producers in the world. We look forward to entertaining music fans with Billboard's own rendition of a televised celebration of music."

The scheduled performers have not just been successful during the period of eligibility for the awards show, but they are still hot on the charts.
