Lady Gaga is a complete 'control freak' when it comes to being photographed, it has been revealed.

According to the Mirror, the 28-year-old singer gave photogs instructions during an event last week, to enhance her snaps by smoothing her jaw line and thinning her arms and legs before they were released.

Photographer Kevin Mazur, who had the exclusive rights to shoot her shows at Roseland, admitted to have retouched the images, adding that he had to get a final approval by Gaga's management team.
