LOS ANGELES -- B.o.B is not only [article id="1647177"]up for five Moonmen[/article] at Sunday night's Video Music Awards; the Atlanta lyricist will have the distinction of being one of the few artists performing two of his hits during the show.

The rapper will be joined by [article id="1647617"]Bruno Mars and Paramore lead singer Hayley Williams[/article] as he delivers his two breakout hits, "Nothin' on You" and "Airplanes," live from the Nokia Theatre on Sunday. Bobby Ray was humbled by the opportunity to share the stage with his collaborators.

"I think it's good that I get to share this moment with two of the people that helped me create two of the biggest songs of the year," he told MTV News at the 2010 MTV VMA Concert to Benefit Lifebeat on Saturday. "It wouldn't be right if they weren't there."

Williams and B.o.B [article id="1647613"]met for the first time during their VMA rehearsal[/article] on Saturday. After performing "Airplanes," Williams will quickly transition to the back of the stage, where Paramore will be waiting to perform their hit "The Only Exception." All three acts share a recording home at Warner Music Group.

B.o.B prepped for his VMA debut with a set featuring his hits at the Lifebeat event, where Ke$ha and the Victorious Secrets also performed.

"I'm just glad to be a part of music history," said B.o.B. "I'm glad to be in the moment. I'm glad to be a part of something that's greater than me."
