Rosie Fortescue is wowed by David's naked shot

Rosie Fortescue was pretty shocked when Louise Thompson posted a very raunchy snap of model David Gandy on Twitter yesterday.

The photo shows a nude David, 33, sitting on a chair with a white shirt slung over his shoulder – and his penis poking out from underneath the material.

‘Maybe one step too far @DGandyOfficial #dong,’ Tweeted Louise, 23.

Rosie, 24, replied: ‘@LouiseAThompson @DGandyOfficial hahaha that can’t be for real.’

Louise said: ‘@RosieFortescue @DGandyOfficial it is! There’s more dick shots.’

The risqué picture of David was taken by fashion photographer Mariano Vivanco and appears in his 2011 book David Gandy By Dolce & Gabbana.

It wasn’t just the Made In Chelsea girls who were enjoying the naughty image last night – their fans were also very excited to have come across it.

‘more please,’ wrote one.
