Young Gaga.
Stefani Germanotta was born on March 28, 1986, born the oldest child by religious, italian parents, Joseph and Cynthia Germanotta. Playing the piano since age 4, she went on to write her first piano ballad at 13 and began performing at open mic nights by age 14. At age 11, the singer attended Convent of the Sacred Heart, a private Roman Catholic school. 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 didn’t fit in in 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. At age 17, Germanotta gained early admission to the New York University’s Tisch School of the Arts. Germanotta lived in an NYU dorm on 11th Street but quickly felt that she was further along creatively than some of her classmates. “Once you learn how to think about art, you can teach yourself,” she says. By the second semester of her sophomore year, she withdrew from the school to focus on her musical career.[14] Her father reportedly agreed to pay her rent for a year on the condition that she reenroll 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.

Current Gaga.
Germanotta had initially signed with Def Jam Recordings at the age of 19 after Island Def Jam Music Group Chairman and CEO L. A. Reid heard her singing down the hallway from his office. After three months, she was dropped from Def Jam,[15] although at the same time, her former management company introduced her to songwriter and producer RedOne, whom they also managed. She moved into an apartment on the Lower East Side, with a futon for a couch and a Yoko Ono record hung over her bed. From there she started the Stefani Germanotta Band with some friends from NYU, recording an EP of her Fiona Apple–esque ballads at a studio underneath a liquor store in New Jersey, becoming a local fixture performing downtown in the LES club scene. Music producer Rob Fusari, who helped her write some of her earlier songs, compared her vocal style to that of Freddie Mercury. Fusari helped create the moniker Gaga, after the Queen song “Radio Ga Ga”. The singer was in the process of trying to come up with a stage name, when she received a text message from Fusari that read “Lady Gaga”. She was known thereafter as Lady Gaga.
