We first spotted the Gossip Girl star pounding the pavements in NoHo, Manhattan, looking cool and casual in a pair of black dungarees.
The stylista paired her fab one-piece with a thin white knit, plus a fancy pair of monochrome shoes and a cross-body leather handbag.
Blake seems to look gorgeous 24/7 and this time was no exception, with the starlet flaunting her natural beauty by ditching the make-up and styling her locks in loose curls.
But fast forward a few hours and Blake showcased a strikingly different (yet equally pretty) look, glamming up for the Chime for Change anniversary party in New York.
We've lost count of the amount of times we've swooned over Blake's evening attire, and we love her latest stunning frock just as much.
The blonde actress - who is married to Definitely Maybe star Ryan Reynolds - opted for a flirty yellow dress complete with leather panels and a cut-out keyhole detail across her bust.
Blake paraded her never-ending pins in pointed gold courts, completing her look with a statement cocktail ring, flower earrings and glowing skin.
And just look at her glossy, golden hair... please Blake, tell us your beauty secrets!
