Lady Gaga got a chance to serenade former President Bill Clinton during a concert to commemorate Clinton's foundation held in Los Angeles on Saturday, October 15, called "A Decade of Difference: A Concert Celebrating 10 Years of the William J. Clinton Foundation."
The concert included performers like Kenny Chesney, Usher, Bono and The Edge, Somali rapper K'Naan and Colombian singer Juanes.
However, it was Lady Gaga who stole the show with two custom renditions of her hit songs "Bad Romance" and "You and I."
Clinton has been celebrating his belated 65th birthday (which was on August 19) with a three-day Hollywood party, including a gala dinner with a performance by Fleetwood Mac's Stevie Nicks on Friday, a brunch on Saturday morning, the Hollywood Bowl concert on Saturday night and a Presidential Golf Outing on Sunday.
Lady Gaga whished President Clinton a happy birthday during her set. "I am having my first Marilyn moment -- I always wanted to have one," the singer said, referring Marilyn Monroe's rendition of "Happy Birthday" which she sang to then President John F. Kennedy in May 1962. "And I was hoping that it didn't involve an accident with some pills and a strand of pearls, so here we are."
The singer then performed several of her hits including "The Edge of Glory" and "Bad Romance" which she changed to "Bill Romance." During her performance of "You and I" she changed the lyrics from "You said sit back down where you belong / In the corner of my bar with your high heels on / Sit back down on the couch where we / Made love the first time and you said to me" to "So Hillary or Bill, sit back down where you belong / In the oval office with those high heels on / Sit down on a couch while we / Watched you charm the whole world in the country."
Proceeds from the concert will go to the William J. Clinton Foundation, which has sought to improve global health, strengthen economies worldwide, protect the environment and promote healthier childhoods.
