The Gossip Girl starlet posed for pictures yesterday (9 July) at the premiere of Turbo in New York's Lincoln Square.
Blake's A-list husband, Ryan Reynolds, stars in the film which hits US cinemas later this month.
Keeping things simple but oh-so-stunning, Blake worked a Burberry frock designed to look like an embellished pencil skirt and slouchy vest combo.
She topped off her outfit with pointed nude courts - a favourite with the celebrity set including Maria Fowler and Chantelle Houghton.
Does the girl ever get it wrong?
