Holly BransonWant an invite to the hottest parties in town?

Then get this lady, Holly Branson, and her friends on your speed dial.

Because they're what you could call the cream of the social crop.

We're talking about the in-crowd often referred to as socialites.

But who are they? And, crucially, what do they do?

Well, most won't - or don't - ever have to see the inside of an office, except to pick up Daddy's credit card, of course.

Although some do head out and get themselves a job, it's hardly your nine-to-five run of the mill position. 

Apart from Sir Richard Branson's lass, Holly, and her bro, Sam, we're talking the likes of Tara Palmer-Tomkinson, Paris Hilton, and Lady Victoria Hervey.

So, tish-tosh off to see the posh pretties who work the social scene for a living.

Yes, it's a tough job, but someone's got to do it, right?
