he did, he mentioned it in a L'Occitane hour with Alexis. He kept whittering on about being on leave at centreparcs the week before wand having taken half the products on air. He said that he had been celebrating his birthday and that he was 40 which REALLY surprised Alexis, the look of surprise was priceless. He took it in his stride and laughed off her "you can't be that old" look, really quite amusing
But the fact he kept it quite until afterwards I thought was really nice, as so many presenters go on and on about events beforehand and to me it comes across that they are just after pressies and cards. Failing that QVC just turn it into a sales ploy.
