Kesha pens song about vagina with mum

London: Kesha has written a song about her vagina with her mother.

The eccentric pop star is extremely close with her mother Pebe - who raised her and her older brother Lagan as a single parent - and the pair often pen tracks about sex and romance together, but on one occasion their musical inspiration turned to Kesha`s private parts. The 25-year-old revealed her that track `Gold Trans Am` from the deluxe edition of latest album `Warrior`, initially started out as an ode to her beloved car. However, Kesha and her mother Pebe turned it into an homage to the singer`s genitals. The blonde added that her vagina is in tip top working order. "Valeted and souped-up and working 100 per cent of the time," she told Q mag. ANI
