Kesha Rose Sebert (pronounced /kɛʃə/, KESH-ə; born March 1, 1987),[5] better known by her first name Kesha (stylized as Ke$ha), is an American recording artist. An active musician since 2005, her breakthrough came in early 2009 after singing chorus vocals on Flo Rida's number one single "Right Round", although she wasn't credited and therefore not paid for this[citation needed]. Her debut single, "Tik Tok", was released in August 2009 to much commercial success. It reached number one in nine countries and set the record for the most digital downloads in a week by a female artist and the total weekly Top 40 Mainstream airplay records in the US. The song also became the longest running number one debut single by a female artist since 1977. Her debut album, Animal, was released in early 2010 and debuted at number one in the US.
