Cheryl Fernandez-Versini copies Simon Cowell's eating habits.
The 'Only Human' hitmaker - who sparked concern with her thin frame during the last series of 'The X Factor' - tailors her diet according to how busy her schedule is but with limited choice on offer when filming the talent show, she just orders the same as her friend and fellow judge.
She said: "I tailor my diet to how many hours I work a day. I won't eat anything that's going to tire me out if I've got to work the next 12 hours. I have to find a balance.
"Doing 'X Factor' boot camp, there wasn't much to choose from, so I'd just eat what Simon was eating."
The 32-year-old singer has a very "strong sense of smell" but finds certain fragrances comforting.
She told Britain's Marie Claire magazine: "I've always had a strong sense of smell.
"I remember going into a room one time and saying, 'Who's been eating cheese and onion?' and sure enough on the opposite side of the room was a packet in the bin.
"Scented candles are a must when I travel, so that I feel comforted wherever I go by the same smell."
