Recent photos of the Material Girl’s biceps that showed her veiny arms and hands in a British tabloid, have caused alarmed among fans and friends.

Madonna has done quite a lot of heavy weights in the past which is what has given her huge biceps. But now, it appears she may have gone over board.

The Metro UK in London photographed the 50-year-old singer leaving a restaurant after having dinner with her model toy-boy, Jesus Luz. Check out the photo here.

Madonna reportedly completes two-hour workouts six days a week to keep her in shape for her Sticky and Sweet tour.
