Stefani Joanne Angelina Germanotta (/ˈstɛfəni ˌdʒɜːrməˈnɒtə/ STEF-ən-ee JUR-mə-NOT-ə) (born March 28, 1986), known professionally as Lady Gaga, is an American singer, songwriter, record producer, actress, and businesswoman. She is known for reinventing herself throughout her career and for her versatility in numerous areas of the entertainment industry. Gaga began performing as a teenager, singing at open mic nights and acting in school plays. She studied at Collaborative Arts Project 21, through New York University's Tisch School of the Arts, before dropping out to pursue a music career. When Def Jam Recordings canceled her contract, she worked as a songwriter for Sony/ATV Music Publishing, where Akon helped her sign a joint deal with Interscope Records and his own label KonLive Distribution in 2007. She rose to prominence the following year with her debut album The Fame and its chart-topping singles "Just Dance" and "Poker Face". The album was later reissued to include the EP The Fame Monster (2009), which yielded the singles "Bad Romance", "Telephone", and "Alejandro".
