Stefani Joanne Angelina Germanotta (born March 28, 1986), known by her stage name Lady Gaga, is an American singer-songwriter, record producer, activist, businesswoman, fashion designer and actress.
Raised in New York City, where she lives, Lady Gaga primarily studied at the Convent of the Sacred Heart and briefly attended New York University's Tisch School of the Arts before withdrawing to focus on her musical career. She soon began performing in the rock music scene of Manhattan's Lower East Side. By the end of 2007, record executive and producer Vincent Herbert signed her to his label Streamline Records, an imprint of Interscope Records. Initially working as a songwriter at Interscope Records, her vocal abilities captured the attention of recording artist Akon, who also signed her to Kon Live Distribution, his own label under Interscope.
In 2008, Lady Gaga came to prominence with her debut studio album, The Fame, which was a critical and commercial success. The record included the international number-one tracks "Just Dance" and "Poker Face". In 2009, her extended play, The Fame Monster, was released to a similar reception, and produced the hit singles "Bad Romance", "Telephone", and "Alejandro". Its accompanying Monster Ball Tour became one of the highest-grossing concert tours of all time. Lady Gaga's second album, Born This Way (2011), topped albums charts in most major markets and generated chart-topping songs "Born This Way", "Judas", and "The Edge of Glory". Her third album, Artpop, is planned for release in 2013.
