Woody Harrelson showed off his birthday suit this weekend during an ocean dip (with buddy Owen Wilson) followed by an afternoon workout around his Miami, Florida home.

All this, completely naked!

Owen, who's in Miami for a flick with co-star Jen Aniston, opted for a more private display of his assets, but didn't seem to mind his companions nudity.

As unusual as it is for anyone to parade around their oceanfront property naked, you'd think a celebrity would be especially cautious about it. But not Woody!
