Otherwise known as Kesha Sebert.

Abstract
Kesha Rose Sebert (born March 1, 1987), better known by her first name Kesha (pronounced /ˈkɛʃə/ KESH-ə, stylized Ke$ha), is an American pop singer and an active musician since 2005. Her breakthrough came in early 2009 after an uncredited appearance on Flo Rida’s number one single “Right Round”. Her debut single, “Tik Tok”, was released in August 2009 to much commercial success. It reached number one in eleven 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.
Kesha was born in the San Fernando Valley of Los Angeles to Pebe Sebert, a singer and songwriter. Her mother, a single-parent, looked after infant Kesha onstage while performing. Pebe was struggling financially while supporting Kesha and her older brother, Lagan, at the time and they had to rely on welfare payments and supplemental nutrition assistance to get by. Pebe moved the family to Nashville, Tennessee in 1991 after securing a publishing deal. She often brought Kesha and her brothers, Lagan and Louis, along to recording studios and encouraged Kesha to sing. Pebe also taught Kesha how to write songs and they would often write songs together when she returned home from school. (read the complete article at Wikipedia)
