Chelsea Handler -- Please, KEEP YOUR CLOTHES ON ... Her Brother Roy Handler Begs

EXCLUSIVE

Sorry, fans of Chelsea Handler's ass and boobs ... one person is on a mission to shut down her Internet nudity streak, because he's tired of looking at it -- her older brother ... which makes sense.

Roy Handler -- a Los Angeles chef who's been on "Chopped" -- told us he was shocked when he went online Wednesday and found Chelsea's rear end staring back at him.

Roy explained Chelsea's reasoning behind the naked rampage -- but also says he's worried about how far she might take this ... especially since Kim Kardashian just upped the ante.
