Clubs like Movida, Pangaea and Boujis have boasted celebrity customers such as Kylie Minogue, Sarah Harding, Lady Victoria Harvey, Beyonce, Jay-Z and even Prince Harry.

But stand in an "exclusive" club early in the night and it's confusing. There are groups of girls sitting and chatting, the bar looks empty, the champagne buckets are devoid of fizz.

But as time goes on a couple of celebrities stroll in, groups of men are led to tables and the gleaming buckets are soon replete with bubbly. Suddenly, the girls who have been waiting, drinkless on the sidelines, gravitate like vultures to men who've paid £600 or more for a table. Some head for the booths that might require a spend of £1,500-£3,000.

Each partying table of two or three men can be surrounded by 10 women drinking champagne. It's perhaps a little taste of why some might stretch their budgets to be the centre of attention.

Sights can be seen. A man in a knee-length leather waistcoat entertains eight women, while standing on a sofa making hip hop hand signals. A woman "Tango'd" with fake tan bares her surgically-enhanced breasts for a photographer.
