[artist id="2542027"]Sean Kingston[/artist] kicks things off Thursday night (September 9) with the Verizon Club Night Concert Event at Hollywood's Playhouse, where Jermaine Dupri will also be spinning. On Friday night, [artist id="2973647"]Jason Derülo[/artist] and Never Shout Never will take the Music Box stage at a concert sponsored by Taco Bell and Feed the Beat.

On Saturday night, "Rock Band 3" and FreeCreditScore.com will present the 2010 MTV VMA Concert to Benefit Lifebeat — The Music Industry Fights AIDS, featuring VMA nominees Ke$ha and B.o.B. The "Tik Tok" singer said she is honored to play a show benefiting such an important cause. "It's really awesome that MTV can bring together incredible musicians over VMA weekend, not only to entertain, but to make a difference," she said. "The world of celebrity is a funny game, although it's a great feeling to have the opportunity to use my fame for a good cause helping those in need."

B.o.B is equally excited to perform for a good cause: "The road to the VMAs has been a wild one. I'm glad to be taking time the night before the big show to support a great organization. Lifebeat's message of HIV prevention is an important one for young people, and I am honored to join them in the fight."

Tickets for the Ke$ha and B.o.B event, with all proceeds going to Lifebeat, are available at Lifebeat.org.

The 27th annual MTV Video Music Awards will be broadcast live from the Nokia Theatre in Los Angeles on Sunday. The party starts with MTV News' VMA Pre-Show at 8 p.m., followed by the main event at 9 p.m. ET.
