The Lost in Translation star was every inch the yummy mummy as she flaunted her post-baby body, sporting a halterneck dress complete with fringed detailing and a thigh-skimming hemline.
But aside from her incredible figure, we couldn't keep our eyes off her fierce hairdo!
From the front, the actress appeared to be rocking a short pixie crop with her platinum blonde fringe styled in a voluminous, swept-back quiff.
But the drama really started when she turned around, giving onlookers a glimpse at her striking shaved undercut which was dyed a contrasting brunette hue.
Very Kelly Osbourne, don't cha think?!
Of course having a shorter hairdo must be much more practical when trying to get ready in the mornings, especially when you've got a tiny baby to look after!
Scarlett and her partner Romain Dauriac welcomed their daughter Rose in September last year. The couple then married in a secret ceremony a few months later.
