Stefani Joanne Angelina Germanotta was born on March 28, 1986, at Lenox Hill Hospital in Manhattan, New York City,[1] to an upper middle class Catholic family. Both of her parents have Italian ancestry.[2]
Her parents are Cynthia Louise (née Bissett), a philanthropist and business executive, and Internet entrepreneur Joseph Germanotta,[3] and she has a younger sister named Natali.[4] Brought up on the Upper West Side of Manhattan, Gaga said in an interview that her parents came from lower-class families and worked hard for everything.[5][6] From age 11, she attended the Convent of the Sacred Heart, a private all-girls Roman Catholic school.[7] Gaga has described her high-school self as “very dedicated, very studious, very disciplined” but also “a bit insecure”.
