LADY GAGA & NICKY HILTON
CATHOLIC SCHOOL CONVENT OF THE SACRED HEART
Back in the late ’90s, New York City was Nicky’s world — and Mother Monster was just living in it! Though the socialite is two years older than the singer, they often crossed paths in the halls of their all-girls school. “They [were] very pretty, and very clean. Very, very clean,” the Grammy winner remembered of Nicky and her big sister, Paris. “It’s impressive to be that perfect all the time.” Sounds like she was just a bit gaga over ’em!
