Lady Gaga and Usher to Honor Bill Clinton, Foundation in Concert Saturday

Lady Gaga and Usher are among the music stars coming together to celebrate former President Bill Clinton and the 10th anniversary of his foundation this weekend.

Highlighting the 65-year-old's efforts to protect the environment, promote global health and stimulate the economy, the Decade of Difference concert honoring the Clinton Foundation will be held at the famed Hollywood Bowl.

The show will stream live on Yahoo at 7 p.m. EST Saturday.

Lady Gaga and others will honor the former President tomorrow.

Kenny Chesney, Juanes, K'Naan and XX are also on the bill for the one night only event, which will also feature an acoustic set by U2's The Edge and Bono.

We've already heard about what happened when Lady Gaga met President Obama. We can only hope she wears something like this tomorrow night as well.
