Lady Gaga was born Stefani Joanne Angelina Germanotta on March 28, 1986, in New York City. The first child of Italian American Joseph Germanotta, an internet entrepreneur, and Cynthia , Gaga has one sister, Natali, who was born in 1992. Gaga is left-handed and began learning to play piano aged four, went on to write her first piano ballad at 13 and began performing at open mike nights by the age of 14. Gaga was raised a Roman Catholic.At the age of 11, Gaga attended Convent of the Sacred Heart, a private all-girls Roman Catholic school on Manhattan's Upper East Side,but has stressed that she did not come from a wealthy background, stating that her parents "both came from lower-class families, so we've worked for everything—my mother worked eight to eight out of the house, in telecommunications, and so did my father."
An avid actor in high school musicals, Gaga portrayed lead roles as Adelaide in Guys and Dolls and Philia in A Funny Thing Happened on the Way to the Forum. She described her academic life in high school as "very dedicated, very studious, very disciplined" but also "a bit insecure" as she told in an interview, "I used to get made fun of for being either too provocative or too eccentric, so I started to tone it down. I didn't fit in, and I felt like a freak."Acquaintances dispute that she did not fit in at school. "She had a core group of friends; she was a good student. She liked boys a lot, but singing was No. 1," recalled a former high school classmate.
Aged 17, Gaga gained early admission to the New York University's Tisch School of the Arts and lived in a NYU dorm on 11th Street. There, she studied music and sharpened her songwriting skills by composing essays and analytical papers focusing on topics such as art, religion, social issues and politics. Gaga wrote a thesis on pop artists Spencer Tunick and Damien Hirst; research that prepared her for her future career focus in "music, art, sex and celebrity."Gaga felt that she was more creative than some of her classmates. "Once you learn how to think about art, you can teach yourself," she said. By the second semester of her sophomore year, she withdrew from the school to focus on her musical career. Her father agreed to pay her rent for a year, on the condition that she re-enroll at Tisch if she was unsuccessful. "I left my entire family, got the cheapest apartment I could find, and ate shit until somebody would listen," she said.
