Vin Diesel sure knows how to turn up the heat after accepting the Ice Bucket Challenge!
The Guardians of the Galaxy star took to Facebook yesterday to share a black-and-white, albeit red-hot pic of him sudsing up in a steamy shower.
In the photo (that was cropped just before it became NSFW...sorry!), the ice-free water falls on the 47-year-old actor's naked, chiseled frame while he throws his head back as if to indulge.
But before teasing fans with a snapshot of his fresh-and-clean manliness, the action-film hero was doing his part to help raise awareness for ALS (also known as Lou Gehrig's disease).
