Oh dear! Chris Brown posts pic of himself licking a woman's bare butt

Chris Brown is beginning to act like he really has bipolar...lol. In the last few days he's been posting and deleting pics on his instagram page...but yesterday he went a little overboard.

Yesterday folks on instagram were joking about "eating booty" and Chris Brown decided to get in on the joke by posting an obscene pic of himself licking a girls butt. Of course he quickly deleted it, but you know...fastest fingers first. Some people got the screenshot. See the uncensored pic after the break...
