A friend at school has a Father who works for the Calvin Klein industry in modeling. He choses all of the models to be used in shots to promote their clothing. Apparently, Daniel Radcliffe was on the list to become a "Trousers" model in London.
Radcliffe is either going to be chosen to promote Underwear or Trousers. It has not been confirmed whether he shall go through or not yet, so fingers crossed for him!
