Singer Celine Dion is struggling to write songs - insisting she is "too busy" to pen new material.

The My Heart Will Go On hitmaker is currently embarking on a year long world tour that ends in February.

But the star, who has sold more than 200 million albums worldwide, reveals the hectic schedule has left her with little time to harness ideas for new tracks.

She says, "I wish I could write songs. I have a lot of ideas. A tune will come into my head and sometimes a lyric, but I never really sit down and try to make something from it. It's just for me. And I think I'm too busy anyway."
