#9 Lady Gaga And Nicky Hilton

Heiress Nicky Hilton knew Lady Gaga before all the fame, name-changing and costumes. The Ladies were classmates at the Convent of the Sacred Heart in New York City, which is a very well-known private all-girl, Roman Catholic school. Hilton just turned 30, while Gaga is only 27 years of age.
