Music icon Madonna is renowned for her fitness and figure despite passing the half-century mark. But she may just be taking her workouts a bit too seriously.

Photos taken showing her bulging veins have made people a little freaked out by Madonna's biceps, instead of impressed by them. They appear a bit alien-like.

The “freakish” Madonna pictures were taken Sunday in London.

The star was eating out with her reported model boyfriend, Jesus Luz, and as she was leaving, some photos of her were taken that have been widely critiqued.

Madonna follows a strict exercise regimen of two-hour workouts six days a week while drinking coconut water to keep energy levels high. Possibly too high.

The pop star is monitored by personal trainer Tracy Anderson, to whom she was introduced by Gwyneth Paltrow. Anderson told the UK's Daily Mail the following:

"I have completely changed Madonna’s body. I told her to forget everything she had been taught before and give up yoga, which can make you look very veiny."

The trainer further distanced herself from the freaky biceps: "Madonna’s very healthy and looks fantastic but those veins have nothing to do with me."

Makes you wonder if Madge took steroids with former boy boy A-Rod.
