Allison Williams Shares Half-On-Half-Off Makeup Selfie

Half-on. Half-off.

Allison Williams shared a selfie on Instagram Friday after taking off just half of her makeup while on the set of HBO's "Girls." The snapshot showed the dramatic difference between the actress' au naturel look and her character Marnie's super-glam appearance.

Took half my makeup off. Guess why Marnie might have this insane look? #90sLips #Season5

This is what happens between shots on set. #Minajesty #Monster #SoMuchMakeup
