Though the Neighborhood Inaugural Ball was peppered with Tinseltown’s finest, the biggest rock star pair in the room wasn’t Demi and Ashton but, of course, the couple of the hour Barack and Michelle. Michelle, dressed in 26-year-old designer Jason Wu’s floor-length ivory gown, danced with her hubby to Beyonce’s ballad At Last. Jill Biden, attired in a strapless red Reem Acra number, danced with VP Joe who worried about his performance on the dance floor.
Leo DiCaprio and Lucy Liu took to the stage to honor the Obamas while Kanye, Mariah, Mary J. Blige, Will.I.Am, Stevie Wonder, Sting, Sheryl Crow and more performed to a festive crowd. Hollywood’s biggest celebs boogied next to the First Couple, with Barack announcing, after his turn on the dance floor, “That’s what’s called old school.”
