"Ridiculously Nervous" Demi Lovato, Jonas Brothers Honored to Perform at Inauguration Eve Concert

You'll have to forgive teen-queen Demi Lovato if she's a bit on edge about performing at a Monday concert helping celebrate no less than the historic, Jan. 20 inauguration of the first African-American president of the United States. "I'm ridiculously nervous, to a point where I don't know what I'll be able to do with myself," the 16-year-old tells TVGuide.com of her pre-show jitters. "I hope I don't fall!"

Lovato calls it a "huge honor" to be a part of the Kids' Inaugural Concert, noting, "It's not just another president. It's [Barack] Obama." Since the concert is airing on Disney Channel, she will sing "Get Back" and La-La Land," two tunes very familiar to her fan base.

Joining Lovato on the musical line-up will be Miley Cyrus, Bow Wow, Usher and a trio of brothers named Jonas. The concert, to be held at the Verizon Center in downtown Washington, D.C., will be hosted by incoming first lady Michelle Obama and Jill Biden (wife of vice president-elect Joe). The audience will include active duty, reserve and guard forces, as well as wounded warriors and families of fallen soldiers.

Nick Jonas, 16, says, "It's absolutely an honor to be able to perform. What we're doing [with this concert] is for the children and families of the military. We could not have been more thrilled to do that specifically."

Besides, who knows, it might come with some perks. "I know there's a bowling alley [in the White House]," says Kevin Jonas, 21. "I just want to hang out!"

Lovato next stars in the Disney Channel comedy Sonny with a Chance (premiering Feb. 8), while the Joni have JONAS arriving on the cabler this spring.
