Cheryl Cole says her favourite look is no make-up and a tracksuit.

The 30-year-old singer loves nothing more than relaxing at home in Newcastle in her favourite sportswear, which she teams with bare skin and a slicked back ponytail.

She told Britain's HELLO! magazine: ''In LA, I always wear sunscreen. In Newcastle, I probably wear no make-up. There's nothing better than a comfy tracksuit, hair scraped up and no make-up.''

The low-key star also finds it hard to relinquish the bad habits of her past - before she shot to fame with Girls Aloud in 2002 - and admits drinking and smoking are her biggest beauty vices.

Asked what the biggest stresses to her skin are, Cheryl confessed: ''Drinking red wine. And I do like the occasional cigarette. It's dehydrating for the skin. And flying. I fly a lot, so I have to keep on top of that.''

The 'Call My Name' singer was once branded the most beautiful woman in the world by 'X Factor' boss Simon Cowell, but she believes beauty comes from within and personality is what makes someone attractive.

Cheryl explained: ''I'm surrounded by beautiful women. Some are aesthetically beautiful and their insides are ugly and it shows through. Then, the most unassuming girl wearing geeky glasses is gorgeous.

''It all comes from inside - that's what makes a woman beautiful.''
