(Cover) - EN Star Style - Mario Testino told Gwyneth Paltrow she was "out of [her] mind" for saying she looked fat.

The Peruvian fashion photographer has shot some of the world's most beautiful women throughout his lengthy career, and recalls a shocking moment back in 2002 when he was snapping movie star Gwyneth.

According to Mario, the stunning actress thought she looked overweight in the image, and he soon made her realise she was talking nonsense.

"She thought she didn't look good, she thought she looked fat and I was like, Are you out of your mind?'

"Gwyneth is a clever girl, and clever don't like to be portrayed as sex symbols. But Gwyneth is a very sexy girl," enthused Mario in an interview with GQ.

Another celebrity to have posed for Mario is pop sensation Lady Gaga. Mario snapped Gaga back in 2009, and he was extremely impressed by her energy.

"When I worked with her there was a discussion about what colour her skin was. And I decided that she would be good almost as a black girl. I liked her exuberance, as she lives everything times ten she's one of the most inspiring girls I've worked with," he beamed. (C) Cover Media
