From humble beginnings she is now a wealthy young lady, but Kesha, who has substituted a dollar sign for the "s" in her birth name, is not popular with everyone.
The American pop singer, rapper and songwriter's lyrics and image have caused several critics to say she is just a "party girl".
Responding to their criticisms she said "If you mean party girl like at a club with a short skirt on with no underwear then no. I've got drunk before but never got a DUI.
"I don't go to clubs, I try not to let my vagina hang out, I don't do drugs, but I think I am a walking good time. I look kind of funny so people think I am messed up all the time, I'm not."
Kesha Rose Sebert was born in Los Angeles to single mother Pebe who is a songwriter. She never knew her father and does not even know his identity. The family were very poor and Pebe brought up her children, Kesha and older brother Legan, on welfare payments and food stamps.
When she was a baby Pebe would often look after her on stage because she could not afford a baby sitter, so she was almost like the old music hall artists of the past who were "born in a trunk."
When she was 4-years-old Pebe secured a new publishing deal for her songwriting and the family moved to Nashville and her younger brother was born shortly afterwards.
Pebe often took Kesha and the boys to the recording studios with her and she would encourage her daughter to sing. She also taught Kesha to write songs and they would often write together when she got home from school.
Although she was studious she dropped out at 17 to concentrate on a career in music. Producers Dr Luke and Max Martin received one of her demo tapes which Pebe had given to Samantha Cox, senior director of writer/publisher relations at Broadcast Music Incorporated.
The producers were impressed by her young, clear voice and they persuaded Kesha to return to Los Angeles to further her career.
In 2005 when she was 18-years-old she was signed to Dr Luke's record label and publishing music company. She would sing backing vocals for other artists, including Paris Hilton as well as writing songs. It was four years before her breakthrough and she caught the attention of the mainstream media and that happened by accident.
She had walked into a recording session with Flo Rida and Dr Luke and Rida was looking for a female voice on the song "Right Round". Dr Luke suggested Kesha and the single became a number 1 hit.
Soon after it topped the charts she signed a multi-album deal with RCA Records through Dr Luke's imprint. Her debut single "Tik Tok" was released towards the end of 2009 and reached number 1 in 11 countries and it topped the American charts for 9 consecutive weeks, making it the longest chart-topping single of the decade to date.
Her debut album "Animal" was released in January 2010 and debuted at Number 1 in the United States, Canada and Greece.
By September 2010 Kesha had sold 2 million albums worldwide and released 3 more top 10 singles from "Animal".
On June 16th 2010 she held a benefit concert with all proceeds going to aid victims of the May 2010 Tennessee floods from her hometown of Nashville and the concert raised $70,000. She also donated 1,000 pounds (450 kg) of dog food to a local animal shelter for pets abandoned in the flood.
Kesha's first award win was "Best New Act of 2010" at the MTV Europe Music Awards and she will do her first headlining tour "Sleazy" in the Spring of 2011 with dates in North America and Australia.
