How thin is too thin? Not even Kate Middleton has escaped the thorny debate. The future Princess evoked quite a debate on her recent visit to Northern Ireland, flaunting her slimmer than usual figure (see the image on the right). While Middleton appeared to be in good health, many commented that she looked gaunt. Old pics of Kate flaunting a white bikini during a 2006 holiday in Spain with Prince William have resurfaced online.
