She might be alarmingly slim, but she's not letting her tiny frame keep her from doing something physically and mentally gruelling -- Cheryl Cole has signed up for a 10-day trek up Mount Kilimanjaro. And how's she training for it? By eating cakes, donuts and other junk food.

According to Fit Celeb, "While most girls would dread the thought of getting bigger, Cheryl can't wait to spoil herself with her favourite treats. She's really looking forward to it as she knows she needs to be fit as possible." For the rest of us, getting in shape means staying away from junk food, but to each her own, I guess ...

Luckily she does know that it's not all cake and cookies: "I don't know about anybody else but I've got blisters on every toe of both feet. We are used to getting in good shape when we are on tour. The dancing really keeps us fit but this is totally different," says Cole, adding that she had just completed a 12-mile walk on the treadmill.
