(Cover) - EN Showbiz - Ke$ha is proud that she "grossed out" Alice Cooper.

The rock god and pop diva recently collaborated on his song What Baby Wants.

Ke$ha was thrilled to show that she can do more than just mainstream pop after penning some disturbing lyrics for the duet.

"I just come up with more crazy ideas to show the world I'm not scared of looking like a freak," she explained. "But I do like that I grossed Alice Cooper out with my lyrical content. It's an impressive moment in my song writing career."

In the track, Ke$ha sings the role of Satan.

Alice has revealed that the 24-year-old penned all of the most unsettling lyrics.

"When Ke$ha and I sat down to write the lyrics to our song, the more disturbing ones were hers," Alice told British newspaper The Guardian. "The ones about, I'll bathe in your blood' and I'm gonna chew through you' [they're all written by] Ke$ha."

This isn't the first time Ke$ha has shown an interest in blood.

Whilst performing single Cannibal on tour the singer appeared to dismember one of the dancers on stage, drink his blood and then spit it at the audience.

The singer joked about her onstage antics.

"I really do devour men at a very rapid speed," she insisted. "And usually by the time I'm done with them, I've literally sucked the blood out of their hearts." (C) Cover Media
