The 'Tik Tok' singer recently learnt how to permanently ink herself using sewing needles and a pen, and tested out her new skill on a "hot" man she met in a hotel.
She said: "A friend of mine told me you can create a tattoo with pen ink and a safety pin and I was like, 'That's amazing. I could give tattoos at anywhere in the world at any hotel.' I saw this hot dude recently and I gave him a tattoo sitting in the lobby of the hotel. I was just like, 'Can I borrow a pen and a sewing kit?' I think I got an admirer out of that one."
The 23-year-old pop star – who is known for being outspoken and for her eccentric dress sense – also revealed she has a unique way of flirting with men in bars.
She added to Paper Magazine: "I usually do something ridiculous like send him over a shot of whiskey and then spank him. Something like that."
Kesha claims to be such a "pervert", she even attempts to pick up men whilst listening to heavy metal music in her Trans Am car.
She added: "I wouldn't say I'm aggressive, but I'm a pervert. I have a gold Trans Am and my favourite thing to do in the world is to drive around blasting Led Zeppelin or Black Sabbath, cat calling dudes. It doesn't work, but it's fun."
