Georgia May Jagger's beauty secret is sleep.

The model insists getting a proper night's rest is the best thing for her looks and says it is even better than make-up at helping her to look good.

When asked her beauty secret, she said: ''Sleep. It's better than a good foundation.''

Georgia also revealed she always wanted to follow in the footsteps of her mother, Texan model Jerry Hall.

She said: ''My mother is very glamorous and effortlessly fab. When I was a child I would watch her apply her makeup and wear beautiful gowns and I wanted to be just like her.''

Although her parents are rocker Sir Mick Jagger and model Jerry, Georgia insists she doesn't like to spend a lot of money in order to look good.

She told America's OK! magazine: ''Have fun with your clothes. Don't spend money on trends, invest in pieces that will last.''

Georgia recently admitted she is surprised her career has lasted so long as she knows it is unusual to stay a popular face.

She said: ''I still don't expect it when I get jobs.

''The reason I thought my own modelling career would be a bit of a phase is because of my mum and (sister) Lizzie, who know what the industry is like. I just thought I'd model for one season. Sometimes models do last a long time, like my mum, but that's not really very common.''
