Pop star Lady Gaga's new album is being worked on by Giorgio Moroder.

The critically-acclaimed producer has revealed that he has written "five or six" tracks for the forthcoming studio record, but he missed a recent studio session with Gaga because he fell ill, reports femalefirst.co.uk.

"I was supposed to be in the studio with (Gaga) a week ago, but I got a cold,` Moroder told Popjustice.

"I'll see her when I'm back. I have about five or six tracks, just basic ideas. Drums, keyboard, bass. I'm going to be surprised, I think - I don't have a clue about the way she's recording. Will she play the piano? Will I, `he added.
