Or at least, that's what she apparently told UK outlet Heat. "I had a tail when I was born," said Ke$ha. "It was a tiny tail, about a quarter of an inch, then they chopped it off and stole my tail. That was when I was little. I'm really sad about that story." This fact would be weird on its own, but it's just one in a series of odd and surprising facts about the pop singer...

Or at least, that's what she apparently told UK outlet Heat. "I had a tail when I was born," said Ke$ha. "It was a tiny tail, about a quarter of an inch, then they chopped it off and stole my tail. That was when I was little. I'm really sad about that story." This fact would be weird on its own, but it's just one in a series of odd and surprising facts about the pop singer...

She Drank Her Own Urine

Why, Ke$ha? Just... why? Apparently, she heard it was good for you and got curious. Her reviews? "It was pretty gross. And I don’t think it really did anything very beneficial to me so, yeah, I wouldn’t probably do it again." Good to know.

In her own words, from US Weekly: "I did sneak into his house because I wanted to give him my demo. So I got his address and I drove up there in my grandpa’s Lincoln town car, parked it right in front of his house. I paid the gardener $5, he shoved my ass under the gate, and then I walked up and the door was unlocked, so I took the opportunity to let myself in. I ended up walking in on him in the middle of band rehearsal. He just kept on playing because he was in the middle of a set. He just gave me this look like, 'Who are you? Why are you in my house?' And then I waved my little homemade demo wrapped in a giant purple bow and set it on his table."

And 1500 out of 1600 isn't too shabby, especially for someone who dropped out of high school soon after.

Ke$ha went to a party at Paris Hilton's house, went into what she thought was a bathroom, and ended up puking in what was actually a closet. And then she wrote a song about it. How exactly did she meet Paris Hilton? Nowhere special, just on an episode of The Simple Life .

She Made a Bra out of Her Fans' Teeth

Again... why? Ke$ha has a thing for wearing people's body parts. She asked her fans to each send her a tooth, and then she proceeded to make a bra, headdress, earrings, and necklaces. Personally, I'm interested in seeing the whole toothy ensemble.

She Had Sex with a Ghost

Yup. Sex. With a ghost. "I don't know his name! He was a ghost! I'm very open to it," she told Ryan Seacrest. Well, hopefully she used protection? And of course, she wrote a song about that, too.
