Lady Gaga performed for her pal Tony Bennett at his 90th Birthday Celebration at NYC's Rainbow Room on Wednesday night. Looking glamorous in a custom Brandon Maxwell gown, Gaga took the stage to perform some of her favorite jazz standards such as "La Vie En Rose" and "Bang Bang," as well as an acoustic version of her hit "Bad Romance." She was later joined by the legendary Stevie Wonder and sang "I Wish" and "You Are The Sunshine Of My Life" for Mr. Bennett. Watch below!
