Celine Dion is "too busy" to write songs.

The 'Think Twice' singer — who has sold over 200 million albums worldwide — says she wishes she was able to pen her own material but struggles to find the time in her busy schedule to harness her ideas.

She said: "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."

The 40-year-old star insists on bringing her family on tour with her, including her 80-year-old mother, husband Rene Agelil and seven-year-old son Rene Charles, and says they help keep her calm and stop her ever getting angry.

She claimed: "Nothing ever makes me angry. I never lose my temper. If I don't like something, I'm going to see someone I'm working with and they'll take care of it. It's not my job to get mad."
