Ke$ha has revealed that she is currently working on new songs about her ex-boyfriend's lack of talent in the bedroom.

The singer released her latest record 'Warrior' in November last year and she told MTV that the wheels are in motion regarding new material.

However, her most recent tracks seem to focus on an ex-boyfriend who didn't quite deliver sexually. Ke$ha said:

"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 penis, and he sucks real bad, so I'm writing about that."

She added: "I wrote a song called 'F**k 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."

The singer resolutely concluded: "Don't f**k with me. Out of all the bitches to f**k with...I'll write a whole album and tell somebody in an interview all about you, all the fake orgasms, tiny wieners."

Ke$ha meanwhile recently showed off a new hair colour, which sees her locks a multi-colour mish-mash of bright tones.
