A brash and driven, Grammy-nominated pop singer and songwriter, Kesha went straight to the top of the Billboard Hot 100 in 2009 with her breakthrough recording, a feature spot on Flo Rida's "Right Round." Her own major-label debut, Animal, followed a year later and made her a bona fide star, reaching number one in the U.S. and Canada behind the international party-time hit "TiK ToK."
