Vin Diesel knows how to turn up the heat — even while he's freezing. The Fast & Furious 7 actor posed naked in a racy shower picture after completing the ALS Ice Bucket Challenge on Tuesday, Aug. 19.

The 47-year-old stripped down for the intimate black and white snapshot and posted it via Facebook. The hunk showed off his muscular body, cut torso and lower abs.

Earlier in the day, Diesel was a bit more covered up in jeans and a white tank top to take on the Ice Bucket Challenge to raise awareness for Lou Gehrig's disease. He was nominated by Guardians of the Galaxy director James Gunn.

As for his nominations? Diesel had some interesting choices. "I challenge the First Lady [Michelle Obama], Angelina Jolie... and [Vladimir] Putin!!! Grrr... #Vinstagram," he wrote via Instagram.
