The other performers who are going to rock the Jane Lynch-hosted awards show are Foster the People and OneRepublic.
Demi Lovato has been announced as one of the musical guests at the upcoming Do Something Awards along with B.o.B. The "Skyscraper" singer and the "Airplanes" rapper are going to be joined by indie rock band Foster the People and Ryan Tedder's band OneRepublic.
"If you are expecting anything less than 'wow,' you've got the wrong awards show," said Nancy Lublin, CEO of Do Something. "We are so psyched to have Demi's first public performance, a hot breakout band like Foster the People, and expect OneRepublic with B.o.B to be very loud!"
Demi gets two nominations at the awards show. She is vying for Do Something Charity Song, facing off Cee-Lo Green, Lady GaGa, Beyonce Knowles and My Chemical Romance. She additionally is up for Do Something TV Star against Paula Abdul, AnnaLynne McCord, Randy Jackson, Eva Longoria and Ian Somerhalder.
The winners will be announced in a ceremony which is going to take place on August 18 and will be hosted by "Glee" star Jane Lynch. Other celebrities who get nods this year include Justin Bieber, David Beckham, Scarlett Johansson, Russell Brand and Will Ferrell.
