Paris Hilton and Nicole RichieParis Hilton and Nicole RichieLife really is tough for Paris Hilton and Nicole Richie.

They get to shop - and call it work.

Ridiculous, no?

The Hollywood duo were filming scenes for their latest series of The Simple Life in LA, and caused quite a stir when they arrived at trendy store Kitson.

Turning up in a yellow school bus, with Paris' mutt in tow, the twosome hopped down and flounced around a bit in their eye-catching frocks before disappearing inside the store.

Not long after, they reappeared, ladened with plenty of bags.

Should this really be classed as work?
