Kesha is an American singer-songwriter and rapper. In 2005, at age 18, Kesha was signed to producer Dr. Luke's record label, Kemosabe Entertainment, and publishing company. Although an active musician since then, singing background vocals and writing songs for other artists, her breakthrough came in early 2009 after appearing on rapper Flo Rida's number-one single, "Right Round".
Her debut album, Animal and her first extended play, Cannibal, were released in 2010. Kesha's irreverent music and image propelled her to immediate commercial success, with Animal debuting as the number-one album in the US. She also achieved two number-one singles, "Tik Tok" and "We R Who We R", and a string of top ten hits from the album and its re-release.
