Surprise!

ABC News has learned that after their scavenger hunt last night, First Tweens Malia and Sasha Obama were paid a surprise White House visit by the Jonas Brothers.

The visit came after Malia, Sasha, and some of their friends from their new school Sidwell Friends saw two new Disney movies -- High School Musical 3 and Bolt -- and participated in a scavenger hunt in which they ran around their new home, learning about this history of the White House. White House ushers had organized a similar scavenger hunt for a young Chelsea Clinton when she first moved into the White House in 1993.

At the end of Malia and Sasha's scavenger late-night hunt, they opened a door to discover their favorite musical performers: Kevin, Joe, and Nick Jonas -- the pop boy band sensation who first exploded on the Disney Channel and also appeared earlier this week at the Kids' Inaugural Concert.
