Becks keeps white and black pants in separate piles

David Beckham arranges his underwear drawer using a colour coding system.

Becks, who suffers from OCD, keeps his white and black pants in separate piles.

‘I wear mostly white, so all the white ones are there,’ he says. ‘Then I have 5 or 6 pairs of black ones, that’s it.’

And David, 33, says he was more than happy to pose in his undies to advertise Emporio Armani briefs.

A giant poster of him wearing a pair of super-tight pants went on display in San Francisco last week.

‘As it was unveiled, I was thinking: “Oh my God…”,’ he tells the Daily Star.

‘But it looks good, I think.’
