Ke$ha plays the keyboard with her breasts - video
The singer quipped that when making music she often lets her chest decide how a song is going to sound.
"The way I wrote songs is a little different," she said. "I always let my breasts choose the chord progression.
"I'm really going to let you in to this intimate process and I'm really just going to let them shine."
Ke$ha is currently promoting her new single 'C'Mon', which is officially released on March 3. The track serves as the second single from her latest album Warrior.
It was recently announced that the singer will star in her own documentary, titled Ke$ha: My Crazy Beautiful Life.
