Kevin, Joe and Nick Jonas also will host the awards ceremony, which airs Aug. 10 at 8 p.m. on Fox.
The Grammy-nominated teen heartthrobs will also perform at the awards that honors the year's most popular teen icons in film, TV music, sports and fashion.
The first round of nominees — as well as additional performers and presenters — will be announced very soon. OMG, we can hardly wait.
Will Robert Pattinson have time to show up? He didn't make the Kids Choice Awards recently. But Taylor Lautner did. Fingers crossed.
Anyway, we'll be on the carpet that day tracking the hot star arrivals with our trusty Flip video cams.
The Jonas Brothers' appearance on "Teen Choice 2009" does interrupt the group's world tour, which spans three continents.
Which JoBro are you most anxious to see? Will they make good hosts?
