Lady Gaga encourages her producers to give her the "craziest possible" ideas for new songs.
The 'Born This Way' singer has been working with Russian-German producer Zedd on tracks for her 'ARTPOP' album and he says she encourages him to be unusual and creative.
He told DigitalSpy.co.uk: "She wants me to do the craziest songs I can possibly do. I'm not thinking about fitting a shoe on the right foot.
"There's just been no limitations at all. No set genre, song length, anything. I'm not afraid to show her the least commercial idea I have. She has a certain way of writing and she likes it to be challenged on the production."
Zedd - real name Anton Zaslavski - added most of the recordings he made with Gaga were after shows on her Born This Way Ball in Asia, where he supported her.
He explained: "We spent a few months together in Los Angeles a while ago and then I went on tour with her in Asia for almost two months. After the shows we would set up a studio and work on the tracks.
"We laid down the musical parts and then I could clean it up in a proper studio afterwards. Seriously, we've been working with the worst speakers you can imagine! That said, her lyrics or vocals won't sound any worse just because she did it in a hotel."
Lady Gaga is currently finishing her Born This Way Ball tour in the US, after which she will turn her attention to completing 'ARTPOP', although no release date has been set at present.
