Motherhood has given Alicia Keys a "reason in life".

The 'Empire State of Mind' hitmaker - who has an eight-month-old son, Egypt, with husband Swizz Beatz - says becoming a mum has changed her life in a "fun" way.

She explained: "Motherhood is heaven. It's so purposeful and such fun. I feel much wiser in the choices I make. I have a reason in life I never had before."

Alicia's new outlook on life is a far cry from when the 30-year-old singer first found success and she admitted her fame was "scary" to begin with.

She told the Daily Mail newspaper: "I suddenly found myself doing tours, TV shows and flying every day.

"Everyone wanted a piece of me and that was scary. Being from New York, I covered that up."

Now with a successful career and a happy personal life, Alicia is looking to the future and first on the agenda is a collaboration with Kings Of Leon.

She said: "For a while I've wanted to do something with Kings of Leon. I definitely want to do it - I'm just waiting for the right moment."
