2015 is already starting off with a bang!

Sexy stud Bradley Cooper took it all off for the newest issue of W magazine-- and we are liking what we see!

Going full-on Saturday Night Fever with a disco-fab outfit draped over his rockin' form -- the Oscar-nominated actor made mouths drop when he dropped his pants. With skin that's looking particularly alabaster, Bradley showed off his muscled figure when he covered his naked body with a white suit, complete with platform shoes.

And while we are big fans of the American Sniper actor's looks -- the 40-year-old hasn't always been so jazzed about his physical appearance.

In 2011, he told British GQ that he had had a hard time, "I was pretty as a child and I felt that I wasn't very manly and that plagued me for years ... Not good-looking, but pretty in the wrong ways; in my mind I looked like a girl."

Well we love how he looks now!
