In July, a representative for Madonna hit out at pumped-up pictures of the pop star, insisting the snaps must have been doctored. The muscly Madonna shots emerged online last month, prompting gossips to suggest the singer had been overdoing her gym work-outs. These photos, however, are 100 percent real. They were taken Aug. 18, 2009 in Munich, Germany.

We don't know why Renee is hitting the gym so hard, but maybe she has a new man in her life? She and Bradley Cooper sparked fresh speculation they are dating after they were spotted together in Spain earlier this month. This photo was taken Aug. 18 in New York City at the premiere of My One and Only.
