Warm front: Sarah's winter look seems to have a common theme...less is more

She told The Daily Star: "I can drink with the best of them and I like to be able to hold my own. I see it as a challenge.

"I like McDonald's burgers and Happy Meals.

"And I've got a thing for kebabs, too. But I don't eat too much of that stuff or it makes me feel a bit ill."

Ultimate: The singer has admitted to loving junk food - but she makes time to go to the gym and loves to walk

But to compensate for her sometimes poor dietary habits, Sarah does hits the gym and dancefloor as often as possible to make sure her takeaway habit does not harm her curvy figure.

"I love to dance," she says.

"I'm very energetic. In fact, I'm actually quite health-conscious.

"I've got a fast metabolism, but I go to the gym, too. At the moment I'm doing loads of work on the pull-up bar and I go walking a lot as well."
