Victoria Beckham has claimed that her favourite store is M&S. And of course she was paid an enormous amount to endorse Tesco with her fellow Spices.

But a supermarket is still the last place you would expect to see the self-appointed beacon of style.

However, even Posh has mouths to feed and there was no escape from the business of everyday life as she hit the mecca for all things organic - and expensive - Whole Foods, in Beverly Hills.

Posh visited America's favourite high-end supermarket - which has a UK branch in London's Kensington - to stock up on store cupboard favourites - cereal and milk.

But Posh will only compromise so much. She eschewed the soccer-mom uniform of sweatpants and trainers in favour of a short sleeveless shift dress, high-heeled sandals and none-too-inconspicuous sunglasses.

Victoria is also clearly not too posh to push and got her bodyguard to carry round her bags.

And could she be hiding a set of green fingers among those extended talons of hers – as she paid particular interest to the plant section of the store.

With David absent, Posh had the assistance of a mountain of a man to help carry her purchases to her car.

Quite what supermarket Tesco will think of Victoria jumping on the Whole Foods bandwagon remains to be seen.

Last year Victoria was famously seen stalking the aisles of Tesco with her fellow Spice Girls in an advert for the supermarket.

Posh abandoned her penchant for expensive goods in favour of a fat paycheck and a shopping session in Tesco as part of a multi million pound Spice Girls deal.

However, Posh made it clear where her supermarket allegiances lie. Just before the Beckhams' move to LA, she said: "You can get most things out there but what I will miss is M&S.

"I missed it when I first moved to Madrid and it is the first shop I go to when I'm back."

Meanwhile one shop Posh will probably not be going to in a hurry is LA's chic boutique Kitson.

Store owner Fraser Ross has criticised Victoria for not promoting her dVb denim line in the store, in person.

He told Life & Style magazine: "I'm fighting right now with Victoria Beckham's people because she lives here in L.A., we sell her line and she won't come in here to do an appearance.

"We have customers asking if she will come in and what am I supposed to tell them? She lives here, she really should come out and support her fans, the people buying her jeans."
