The 'Fight For This Love' hitmaker, who split from footballer husband Ashley in 2010, loses her appetite when she has personal problems, reported Femalefirst.
"Cheryl tells us that if she gets stressed with men, she can't eat. When she went on 'Popstars: The Rivals', I remember (Girls Aloud) were all upset because they were told to lose weight. That was ridiculous.
"I know Cheryl loves her takeaways, and she did tell us that she wanted to lose weight, cos (sic) she joked she'd become a pop star and put on weight and that definitely wasn't what was supposed to happen," said Armstrong.
However, she said Cole will indulge in her favourite takeaways when relaxing at home with her family in Newcastle.
"She likes to dress down when she's with us. She's in tracksuit bottoms - sometimes pyjamas - and no make-up and she looks stunning. We always have a Chinese takeaway - her favourite is duck."
