The 'Rude Boy' hitmaker keeps her svelte physique toned and trim by "walking for miles" through airports while she is jetting between performances all over the world.

She said: "I keep fit by walking through so many airports. You end up walking for miles in those places!"

The Barbados-born beauty also admitted she loves cooking up hearty, calorific meals - including lasagne and shepherd's pie - for her friends.

She added: "I love cooking, but I don't get to do it as often as I would like, because I travel so much. My best friend and I are always cooking together. She will maybe do lasagne or shepherd's pie.

"Food from Barbados is so different from British food, but we have a lot of things that are similar ' such as shepherd's pie."
