Making for quite the night to remember, Lady Gaga was among the star-studded lineup of performers taking the stage at “A Decade of Difference: A Concert Celebrating 10 Years of the William J. Clinton Foundation” in Los Angeles, CA on Saturday night (October 15).

Held at the iconic Hollywood Bowl, the charitable event was organized to raise awareness around Clinton Foundation’s efforts to improve global health, strengthen economies worldwide, promote healthier childhoods, and protect the environment.

With the festivities also being a belated 65th birthday tribute to Bill Clinton, Gaga delved into her set by belting out a Marilyn Monroe-esque rendition of "Happy Birthday" to the former U.S. Commander-In-Chief before transitioning into her hit single "Born This Way."

Speaking to the sold-out crowd, the 25-year-old singer said, "I always wanted a Marilyn moment -- but didn't want it to involve pills and pearls."

Other stars joining in on the festivities included fellow performers such as Usher, Kenny Chesney, Bono & The Edge of U2 and Stevie Wonder with Ashton Kutcher, Lindsay Lohan, Ellen DeGeneres, Portia de Rossi and Jason Segel also turning up for the fun-filled extravaganza.
