Kesha Rose Sebert (born March 1, 1987), better known by the mononym Kesha ( /ˈkɛʃə/ KESH-ə, stylized Ke$ha), is an American pop singer-songwriter and rapper. In 2005, at eighteen, Kesha was signed to Dr. Luke's record label and publishing company. Although an active musician since then, singing background vocals and writing songs for other artists, her breakthrough only came in early 2009 after appearing on Flo Rida's number one single, "Right Round."

Her debut single, "Tik Tok", released in late 2009, reached number one in eleven countries. Her debut album, Animal, was released in January 2010 and debuted at number one in the US, Canada and Greece. By September, Kesha had sold two million albums worldwide and released three more top ten singles from Animal. The album was re-released with a companion extended play, Cannibal, in November, preceded by the chart-topping lead single, "We R Who We R".

Kesha has cited artists such as Madonna, Debbie Harry, Queen, Johnny Cash, Aaron Neville, Bob Dylan and Beastie Boys as musical influences. Her music incorporates elements of dance-pop, and she uses a spoken word rapping style on many songs.
