I haven't read them, to be honest all of the hype has actually put me off them. I bought them to take on holiday and left them there unopened.
Anyway, I heard on Daybreak earlier that they are bringing out a 50 shades of grey fashion range. Gimp mask & handcuffs????
I've just tried to find my favourite 50 sheds of grey tweet, but alas it's no longer there. It was along the lines of her screaming 'I said gimp me, not chimp me'
