The singer, who recently claimed to have had sex with a ghost, is apparently a huge fan of the guitarist and said it is her dream to one day collaborate with him on a track.
She told: "Keith Richards is the end-all and be-all for me. I'm gonna keep trying to work with him until the day I die probably."
Ke$ha releases her second album "Warrior" on December 3. The first single off the new album "Die Young" was released in the US on September 25, and is due out in the UK on November 25, according to NME.
Meanwhile, the singer's autobiography goes on sale. "My Crazy Beautiful Life" will show a "not all glamorous" side to her life. Speaking about her 192 page memoir via publishers Simon and Schuster, Ke$ha said: "In less than three years, I've gone from being the worst waitress in LA to living out my childhood dreams of singing my songs to people all over the world. Sometimes, it feels as if the last few years have encompassed a few decades."
