Lady GaGa's high school yearbook picture.

The way she began working with her voice coach at age 14 was a chance encounter.

"I was singing [I Want It That Way] to myself in a shop down the street from my house, when the store owner, who happened to also be a musician, pulled me aside and slipped a phone number in my hand. He told me his uncle was a highly respected voice teacher who he thought would like to work with me. I called him up and remember his words, “I work with Grammy Award Winner Christina Aguilera, Bono of U2, Mick Jagger and as the list got larger I got more excited. " —Lady Gaga
