Lady Gaga and Usher have both signed on as performers for the 10th anniversary concert honoring Bill Clinton's charity organization, the William J. Clinton Foundation. Bono and The Edge of U2 have also been recruited to headline the former president's bash at the Hollywood Bowl, which is slated to occur on Oct. 15.

Over the course of 10 years, the William J. Clinton Foundation has raised roughly $10 billion dollars for charities that are close to Clinton's heart, including HIV/AIDS treatment, the improvement of healthcare worldwide, and lending assistance in poverty-stricken areas (including giving food to those are starving throughout the world). According to The Hollywood Reporter, the celebration on Oct. 15 will also serve as a belated birthday party for the 42nd President of the United States, who turned 65 on Aug. 19.

More performers and celebrity guests will be announced throughout the next month. Tickets will also be made available to the public so that they can partake in the festivities as well. If you aren't going to be in the area and were hoping to get in on the fun, don't worry -- Yahoo has exclusive rights to the show and will stream the concert online on Oct. 15.
