Kesha pens revenge song

Singer Kesha is busy writing a song to get back at an ex-boyfriend.

The 26-year-old has recorded a new track called "You suck a**", reports contactmusic.com.

"Right now my new songs are more dude-oriented, because I recently had this boy just be a total piece of s**t, douchebag piece of garbage to me. And he has a tiny p***s, and he sucks real bad, so I'm writing about that," she said.

"I wrote a song called 'F**k you', but then that title was already taken, so 'You suck a**' is another title. It's talking about fake orgasms every time I had sex with him, and how I pawned all the diamonds he bought me in Vegas and bought some Chanel earrings," Kesha added.
