Lady Gaga and Usher were just two of the big names at Saturday's A Decade of Difference concert, and not only did Gaga serenade the former president and drop an F bomb during the show, but Usher danced up such a storm he ripped his pants!
The concert celebrated the tenth anniversary of the William J. Clinton Foundation, and it also featured performances by Juanes, Kenny Chesney, K'naan and The Edge & Bono. Guests and speakers included Ashton Kutcher, Lindsay Lohan, Barbra Streisand, Ellen DeGeneres, Portia DiRossi and Maria Bello, and Ben Stiller, Matt Damon, Sean Penn, Jack Black and Kevin Spacey all taped bits for the show.
