Ellie Goulding used to eat nothing but chocolate.
The 'Starry Eyed' hitmaker admits she was "badly addicted" to sugar when she was a student and horrified her friends with her unusual eating habits.
She said: "I remember being so badly addicted to sugar that I could eat two big Galaxy bars in one day and nothing else.
"I was terrified of eating potatoes or rice or any kind of carbohydrates but I would still have loads of chocolate every day. It made no sense.
"My friends were so worried about me because I would come to their houses with bars of chocolate and when they'd ask what I'd eaten that day I would tell them, 'Chocolate for breakfast, chocolate for lunch and then an apple and a salad.'"
However, Ellie thinks an eating disorder "would maybe be too strong a term" for her habits but admits she wasn't very healthy and her diet was "extreme".
She said: "I definitely thought about food in a way that wasn't healthy and ate in a very extreme way that should have given me diabetes."
And these days, the blonde beauty - who is in a relationship with McBusted bassist Dougie Poynter - is much healthier thanks to her "balanced" approach to nutrition.
She told Glamour magazine: "Now that my attitude to nutrition is balanced, I feel and look better.
"My skin is balanced, I feel and look better. My skin is brighter and my eyes are brighter - and when I look at myself in the mirror, I've got far fewer hang-ups."
