Explicit photographs apparently showing Kesha involved in several sex acts have been leaked onto the internet.
The images feature the `Tik Tok` singer kissing and biting the bottom lip of a bearded man in one shot and receiving oral sex in another, they were posted on gossip blogger Perez Hilton`s adult orientated website, Unrated Perez.
The 23-year-old pop star has not yet confirmed if it is her in the pictures.
Kesha recently revealed she had split from her drummer boyfriend Alex Carapetis because he had been acting like a "woman".
She said: "We`re not so dating anymore. He had a Keith Richards vibe to him, but then he started acting like a woman, and I just can`t handle that."
However, the blonde beauty already has ideas on how to land a new man.
She explained: "I usually do something ridiculous like send him over a shot of whiskey and then spank him. Something like that. 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."
