Lady Gaga & Nicky Hilton

The pop icon and hotel heiress attended Convent of the Sacred Heart, an all-girls Roman Catholic school in New York City. While they were there at the same time, they weren’t in the same grade. Gaga is a few years younger than Nicky, the little sister of Paris Hilton.

Even though Gaga is both a singer and actor now, she didn’t always have the easiest time in school. According to her mom on CBS, Gaga was humiliated, taunted and isolated during those years.
