London, February 27 : 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)
