If Victoria Beckham thinks she is going to be able to acquire new girlfriends effortlessly among Hollywood's showbusiness elite, she should think again.

Just a few days after setting foot on American soil, the self-styled fashion icon may already have alienated vast swathes of the country's female celebrity population by criticising their tatty dress sense.

In the interview in the LA Times, Victoria first defended her own dress sense, saying: 'I don't want to change the way I dress. This is me, and if people like it - great.

Then speaking about the paparazzi pictures of Hollywood stars she has seen on the pages of glossy magazines, she went on: 'They dress down quite a lot here, don't they?. It seems to be in keeping to go to Starbucks in tracksuit bottoms and Ugg boots.'

She went on: 'I have one pair [of tracksuit bottoms] for non-photographic opportunities only. Underground car parks are fine, but aside from that, no.'

While the public and media have given her husband David a fantastically warm reception, the same cannot be said of the luke warm welcome Victoria has had.

Critics have been less than thrilled by her fly-on-the wall documentary, Victoria Beckham: Coming to America.

A New York Times reviewer conclued that the programme proved "there is no such thing as celebrity ditz-fatigue."

Her latest comments will certainly will not endear her to Hollywood's women.

What the Spice Girl has clearly failed to notice in a town which is wall-to-wall with stars, is that none of them feel the need to dress up just to go to the coffee shop - like she clearly does. The dressing up in Hollywood is usually saved for dressy occasions - like the Oscars or Emmys for example.

On a daily basis, the biggest names can be seen happily slouching around in the very tracksuit bottoms and Ugg boots look Mrs Beckham is complaining about.

In the last few months alone Penelope Cruz, Lindsay Lohan, Eva Longoria, Nicolette Sheridan, Pamela Anderson, Charlize Theron, Paris Hilton, Kirsten Dunst, Jessica Simpson, Cameron Diaz, Drew Barrymore, Demi Moore, Britney Spears and Pink have all been photographed in Los Angeles wearing just that look.

And as the accompanying LA Times editorial points out: 'Unlike most celebs, she (Victoria) doesn't dress down in slouchy T-shirts, flip-flops and jeans. Beckham dresses, really dresses, for every occasion. Her wardrobe notes might read something like this: June 11: Opening pitch at the Dodgers game - short-shorts and debut of Dries Van Noten platform sneakers. Jan. 16: Dinner date with Katie at the Ivy - frilly organza Giambattista Valli dress, very ladylike. June 3: MTV Movie Awards — vintage zebra-print Azzedine Alaia mini with pink satin bra peeking out. So 1980s, so MTV.'

The LA Times journalist also goes on to describe how Mrs Beckham is wearing 'a mini-dress for a coming-to-L.A. interview' which is 'so short that you can't help but get the occasional glimpse of her pink panties'.

The article is sure to send ripples around Hollywood's fragile starry circles - and give America's chatshow hosts further ammunition.

Pretty in Pink: Posh takes America by storm

Just last week, prior to the Beckham's arrival, Victoria was the butt of endless jokes for being too pouty, miserable and over-dressed.

Mrs Beckham also uses the interview to attempt to stamp her fashion credentials on the veteran showbusiness set. Speaking of her collection of clothes, she said that she has kept every outfit, handbag and pair of shoes she has ever worn.

'I would love to have a record of everything I wore on every occasion. If I wasn't so busy with the children I would love to do that.'

She also has hundreds of handbags - including dozens from Hermes. 'I think of them as an investment,' And someday, when I'm lucky enough to have a girl, I will pass them along to her.

The article also reveals that Mrs Beckham plans to bring out a new version of her style bible That Extra Half Inch to help America's wayward stars to dress properly.

In the meantime, she says she is working on her own line of jeans and sunglasses which will be stocked in stores across LA.

'This is just the beginning,' she says of her fashion exploits. 'I want to still be doing this in 20, 30, 40 years' time. I was never going to be the best singer, dancer or actress. I worked hard at it and I did a pretty good job.

'But with fashion, I'm good at it.'
