Anna Wintour and Lauren Sanchez arrive together in the same car at PFW event

Nicknamed 'nuclear Wintour' for her frosty nature, Dame Anna - the legendary Vogue boss, wouldn't be seen arriving at Paris Fashion Week with just anyone.So it's no wonder the rumour mill went into overdrive when she stepped out of her car at the Schiaparelli show yesterday with none other than Jeff Bezos's wife, Lauren Sanchez.The duo's outing has done nothing to dampen speculation that the Amazon tycoon is one step closer to purchasing Conde Nast, the parent company of 'fashion bible' Vogue.
