Now what in the heck is Lauryn Hill wearing?

Who left the gate open?! Seriously. Lauryn Hill is killin' em -- but not so softly!

L. Boogie was performing in Brooklyn at the 25th Annual Martin Luther King Jr. Concert Series Monday -- where she was spotted wearing an '80s remix of Grace Jones crazy meets Ronald McDonald rouge with a dibble-dabble of Thriller era Jacko. Who's baaaad?!

She will cut you -- with those razor-sharp earrings! Double-up! Use your accessory as a weapon! Oooh la la la!

She looks like a damn rooster in that outfit! Your thoughts....
