'Gold Trans Am': Ke$ha Wrote Recent Single About Her Vagina With Her Mom

Ke$ha somehow always finds a way to outdo herself.

The urine-drinking, cannoli-fellating, beard-licking pop star just took it a step further, speaking to Q Magazine about the inspiration behind one of her latest singles, "Gold Trans Am."

"It began as a song about my car, which is a gold Trans Am, and it works about 40 percent of the time," Ke$ha told Q Magazine. "I don't have another car because I love that one so much. But then like all great pop, it became a metaphor for something else -- my p---y."

"My vagina is in tip-top working order," she continued. "Valeted and souped-up and working 100 percent of the time."

Lest she stop there, Ke$ha went on to explain that she gets help on songs like "Gold Trans Am" from none other than her mom. "We write songs about boys and sex together," she said. “That may not be normal to the average psychiatrist out there but I think it's pretty cool."

"Gold Trans Am" is featured as a bonus track on the deluxe edition of Ke$ha's latest album, "Warrior."
