Shrieks in the State Dining Room (OMG!)

First Lady Michelle Obama hosted more than 100 students from across the country today at the White House to take part in a workshop called “The Sound of Young America: The History of Motown.”

According to a White House release, the interactive event focused on the history and legacy of Motown, and featured performers who will be on hand at a concert later this evening to celebrate Black History Month.

Students got to hear from musical greats like Berry Gordy, Smokey Robinson, and John Legend. Then, at the conclusion of the event, there was one more surprise guest.

"Before we go, I think I have one more special guest for you. Please put your hands together and welcome Nick Jonas and John Taylor!" the GRAMMY Museum’s Executive Director and event moderator Bob Santelli exclaimed.

Cue shrieking girls.

The youngest of the Jonas Brothers came into the East Room and treated the crowd to a rendition of The Temptations' "Sugar Pie, Honey Bunch."

While Michelle Obama left before the song, the Jonas Brothers did sing for Michelle Obama and the First Daughters at the "Kids' Inaugural: We Are the Future" event in January 2009.
