Lady Gaga

Raised on a musical diet of Michael Jackson, Cyndi Lauper, the Rolling Stones and the Beatles, Lady Gaga brings a sense of theatrical fashion and attitude to her dance-inspired, electro-rock performances. Named after Queen's "Radio Gaga," the pop fashionista took the fast lane to success, starting at age four when she learned to play piano by ear. At 14, she began performing at open-mic nights in and around New York City's Lower East Side. After graduating from Convent of the Sacred Heart school (the elite private institution Paris Hilton attended), Gaga earned a coveted spot at the famed Tisch School of the Arts. Soon after, she started writing songs for the Pussycat Dolls, and at age 20, she was signed to Interscope Records. In 2009, she became one of pop culture's most ubiquitous figures, with the songs "Just Dance" and "Pokerface" dominating the pop charts and her public antics (Kermit dresses! A possible penis?) dominating discussions from TMZ to the blogosphere. Though Gaga's 2009 tour with Kanye West was cancelled, the fact that she was the one to call it off only confirmed her status as one of pop's reigning divas.
