Listen to Ke$ha on iHeartRadio

It's becoming more clear where Ke$ha inherited her eccentric personality.  The singer is telling Q Magazine that it was her mother, Pebe, who helped her to write the lyrics for a song called "Gold Trans Am," which is on the new deluxe edition of her Warrior album. 

Ke$ha says it began as a song about her car, but like all great pop it became a metaphor for something else - her lady parts. 

The singer says she and her mother are very close and often write songs about boys and sex together.  Ke$ha admits that their relationship "may not be normal to the average psychiatrist out there," but she doesn't mind. 

She adds that people should feel free to indulge their fantasies "as long as you're not hurting anyone."
