Joe Jonas is set to present at the 2011 MTV Video Music Awards, and he has a very specific job to do when the show goes live Sunday night (August 28) from the Nokia Theatre in Los Angeles: He'll be supporting his "See No More" pal Chris Brown.

"I'm gonna be introducing Chris Brown, his performance, which is going to be a lot of fun," Jonas told MTV News at Saturday night's Lifebeat concert, less than 24 hours until show time. "And to be able to work with Chris and see him perform, I love watching him play."

Long before the two would work together on Jonas' Fast Life single, Brown made his star-making VMA debut four years ago, lighting up the show in sparkling Las Vegas. "I remember his VMA performance couple years back," Jonas said. "It was unreal: him dancing on the tables. [It] should be exciting to see him play again."

While fans went crazy for his 2007 performance, Brown is set to up the ante this year. Choreographers Rich and Tone recently dished to us that Brown plans to go hard when he takes the stage.

"You're definitely gonna see Chris Brown in a 1,000 percent mode," Rich said. "Of course, everybody knows he can sing, he has great music, and aside from that, you're going to see that he's an amazing dancer."

In addition to performing, Brown is up for two Moonmen for Best Hip-Hop and Best Collaboration for his eye-catching Colin Tilley-directed "Look at Me Now" video, featuring Lil Wayne and Busta Rhymes.

The 28th annual MTV Video Music Awards will air live Sunday from Los Angeles at 9 p.m. ET/PT, following the Selena Gomez-hosted pre-show at 8. See the list of nominees, revisit last year's highlights and vote for Best New Artist by visiting VMA.MTV.com.
