Who's The Designer?Who's the designer?It's not someone you'd usually associate with fashion, that's for sure.

So just who is behind this jockey silk?

It's Celebrity Big Brother star and Diet Coke lover, John McCririck.

John is one of a bundle of British stars who have got their sketch pads out to design a jockey shirt.

Kym Marsh, Jodie Kidd and Gordon Ramsay have also let their creative juices run.

The shirts, which will be available to buy in an online auction, will help raise funds for the Alder Hey Hospital's Imagine Appeal.

Now take a look at who came up with what in the gallery above.
