Victoria Beckham, famous for being extra conscious in front of the camera, shocked everyone after pictures emerged showing her pins looking far from perfect.
The usually faultless Posh was snapped with strange marks both above and below her knee, making her legs look horrifying.
The Spice Girl was photographed while going for a shoot in harsh sunlight in Beverly Hills.
"She's obviously lost weight. I suspect she works out, which is why on her thigh you can see in sharp relief the outline of the quads muscle," The Sun quoted Sun GP Carol Cooper, as saying.
Meanwhile, Beckham, who recently moved to the US with her family, seems to have upset her LA neighbours after she criticised Hollywood stars' fondness for dressing down.
In her first US interview, Posh Spice said that American actresses love wearing tracksuits and Ugg boots.
"They dress down quite a lot here, don't they? It seems to be in keeping to go to Starbucks in tracksuit bottoms and Ugg boots," she said.
