Ke$ha revealed she uses her breasts to help her write songs and even gave a demonstration.
During an interview, she was asked to play the keyboard, but no one expected her to lean forward and perform some music with her boobs.
She said: "The way I wrote songs is a little different. I always let my breasts choose the chord progression. I'm really going to let you in to this intimate process and I'm really just going to let them shine."
Ke$ha says fans will see her drinking her own pee in the upcoming documentary about her life.
"Ke$ha: My Crazy Beautiful Life" is scheduled to premiere on MTV in April, and viewers can expect some strange things from the series,
Ke$ha says: "I was told drinking my own pee was good, I was trying to be healthy ... Somebody tried to take my pee away from me and I said, 'That is mine!' So I snatched it up and took a chug and it was really gross so I don't do it anymore."
