Guess who else is writing a song about her ex-boyfriend, other than Taylor Swift? During an interview with MTV, "We R Who We R" singer Ke$ha, without a doubt, tops Swift's level of anger towards her inspiration: former boyfriends.

Ke$ha explains about her new track called, "U Suck A--," which describes her recent failed romantic relationship with her ex.

"Right now [my new songs are] more dude-oriented, because I recently had this boy just be a total piece of s---, douchebag piece of garbage [to me]," Ke$ha says in unhindered rage. "He's just a lying sack of s---, balls, s--- -filled b--- sack, he's just a giant pair. And he has a tiny penis, and he sucks real bad, so I'm writing about that."

The outspoken 26-year-old pop star definitely has zero filter, and she is trying to get back at her former boyfriend, by expressing her immense hatred and disgust toward him through her music. Ke$ha continues on with explaining how she has came up with the title of her new material, and reminisces her bad memories with her ex.

"I blocked him, because he was being a f---ing psychopathic piece of garbage dogs---," she vents. "So I wrote a song called 'F--- You,' but then that title was already taken, so 'U 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."

Finally, the enraged singer warns her ex, "Don't f--- with me. Out of all the b----es to f--- with. I'll write a whole album and tell somebody in an interview all about you, all the fake orgasms, tiny wieners... don't f--- with me."

Clearly, it's not good to get on Ke$ha's bad side. The man in question... better watch out.
