The X-Factor judge, who this week asked her fans to help choose the cover of her autobiography, also told The Times that she gets very possessive when it comes to food:

“One of my nicknames is 'the beautiful pig. Eyes bigger than my belly, massive portions. I could probably sit here for like, three hours going through one meal and I won't finish until it's all done.

"The only time I'm a diva is with my food. I hate sharing. I'd rather go into the kitchen and make someone a whole new meal than give them some off my plate."

The ‘Young’ singer, who releases new single, 'Live It Up,' on September 9th, also admitted in the interview that her life would now be very different if she hadn’t found fame:

"I'd be living with a drug dealer in a council flat. I can imagine having a baby because there's nothing else to do."
