Whoa! See Lindsay Lohan in Platinum Blonde Bob, Glasses, All-White Outfit
LiLo switches it up yet again!
Showing off her still-sharp comedic skills, the Liz and Dick actress, 26, kept completely silent for the bit -- and was practically incognito in a New Wave-style platinum blonde bob wig, cat-eye glasses and a feathery all-white actress.

As Fallon (in a similar outfit!) crooned "Let us played with your look" over and over again, Lohan grabbed a wad of Crisco from a bedazzled container and worked it into the hair of an agreeable male audience member -- giving him a greasy faux-hawk.
Lohan (in character) awkwardly exited the stage after Fallon's character collapsed. In real life, the often-troubled star bonded with Fallon, 38, at NYC eatery Tao in the aftermath of Hurricane Sandy.
Watch the hilarious clip now.
