Blake seemed especially proud of the way she'd been able to bounce back so quickly after delivering her first child over the Christmas holiday.
the New York Fashion Week which kicked off February 12, made the 'Gossip Girl' star step out, as she showed off an incredibly sexy figure of hers.
The former 'Gossip Girls' star displayed a remarkable flat tommy while supporting her friend and designer, Gabriela Cadena's show case.
The new mom sported black and white Gabriela Cadena bodycon dress which fitted her every curve.
The 27-year-old actress made sure her tiny waist and perfectly long toned legs were also on full display in her clingy dress.
To add a pop of colour, the "Green Lantern" star carried along a yellow clutch and white high heels with crisscrossing straps were fashion-forward touches.
Blake seemed inwardly conscious of her amazing, post-pregnancy transformation at this star-studded event, her first since welcoming a baby girl with husband Ryan Reynolds over the Christmas holiday before New Year's.
