R. Kelly's Fan Grabs His Chestnuts During Xmas Concert

One R. Kelly fan definitely made Santa's naughty list when she got up close and personal with the singer's junk making it a very, very merry Christmas in the D ... Detroit, that is.

Kelly kicked off his "12 Nights of Christmas" concert Friday night at the legendary Fox Theatre, but this is clearly not a holiday show for the kids. It's a much different take on "The Nutcracker."

Kelly's reaction to the grabby fan is priceless, considering he was kinda asking for it.
