R. Kelly is known for his weird antics, both in and out of the spotlight, so it didn't come as that big of a shocker when he showed up sporting a black face mask to the Grammy Awards in 2004. Is it just us, or does R. Kelly look like he could replace Antonio Banderas in the next Zorro flick with that not-so-concealing disguise? He's even got the skinny little stache going on, a la the O.G. Zorro from the old-school TV show. En garde!
