Arriving at the Vanity Fair party at the exclusive Hotel du Cap at 11pm on Saturday, I walked down to its poolside terrace, shrouded in blue party smoke, and came across a lone party guest (a drummer for Mick Jagger, I later discovered). He was hiding in a bush, speaking urgently on his mobile: "Can't we hire a helicopter to get to Naomi's? Like, exactly how far is St Tropez? Just tell the pilot to land on the grass here. There's a lot of smoke gushing out of some machines they have fixed up, and some freaky monster light show, but he can land, and Mick and I can rush out," said the voice.
