Yes, I remember Renee who also modelled for him - but she has long since disappeared (where?). No doubt that Ali is attractive, but I think she's a slice short of the full loaf; on today's show Julia asked her if she was wearing the 'clear' necklace, - no answer, again Julia asked, - no answer; then on the close up monitor it was revealed she was wearing a 'grey' version, the same as Julia. Surely the woman must have known what she was wearing. I swear some of these models have the lights on but no-ones at home mentality.
As for Simon, he can be cutting, in that 'gay man' sort of way, so its to be expected, but I do find it a bit naff that ageing designers/popstars (fashion or otherwise) still try to be pensioner 'edgy' i.e. Simon only wears Converse trainers. I KNOW, its their choice, but just saying.
