Someone's been loading up on HGH and Power Bars!
The supermodel tweeted a pic (above) showing off the product of all of her workouts, which she posted a pic of earlier in the day (below).
She captioned the muscle pic, stating, "I may have over done it with the gym…??"
You can't fool us Bar! We know that arm belongs to the beefcake hiding behind you.
