Stefani Joanne Angelina Germanotta (born March 28, 1986), better known by her stage name Lady Gaga, is an American singer and songwriter. She initially performed in theater, appearing in high school plays, and studied at CAP21 through New York University's Tisch School of the Arts before dropping out to pursue a musical career. After leaving a rock band, participating in the Lower East Side's avant garde performance art circuit, and being dropped from a contract with Def Jam Recordings, Gaga worked as a songwriter for Sony/ATV Music Publishing. There, Akon noticed her vocal abilities and helped her to sign a joint deal with Interscope Records and his own KonLive Distribution. More: en.wikipedia.org.
