She stunned fans earlier this month when she stepped out looking slimmer than ever in a tight red dress.

But now Peaches Geldof has displayed the full extent of her weight loss by posting a picture of herself on Twitter looking tiny in a baggy gold Vivienne Westwood dress.

The 22-year-old shared the picture along with shots of all her new purchases after a Vivienne Westwood shopping spree.

The starlet, the daughter of Bob Geldof and the late Paula Yates, splashed out on four dresses by the British designer, before tweeting shots of each of them and asking for fans' opinions.

However, it was the shot of her in a gold Westwood number which showed her incredible weight loss.

Peaches is estimated to have lost around one-and-a-half stone since March, slimming from 10 stone to  eight-and-a-half stone.

But after reports that she was looking too thin, Peaches was quick to slate any criticism.

She claimed that she had also embarked on a healthy diet and keep-fit regime after meeting her boyfriend, musician Thomas Cohen.

She tweeted earlier this week: 'To those telling me I look skinny and to eat something, I can assure you I've just cut out eating crap.

'I still eat like a horse, guys!'

She then added: 'All these "Peaches Geldof: so skinny",  "Peaches Geldof's drastic weight loss" articles are becoming boring.

'I eat more healthily now. That's it.

'Obviously I'm going to look thinner if I don't sit around eating pizza and chips. It's just how the body works. You are a product of what you eat.'

When a fan asked her for tips, Peaches replied: 'Healthy diet, lots of fresh fruit and veg and no bread/ wheat.'

Good work, Peaches. Keep it up...and hopefully you will disappear completely like the vacuous empty space you are.

Healthy changes will bring about lifestyle change to be kept. A fad or diet will not.
