Keira Knightley Is Beautiful In Midnight Blue Valentino Dress

Keira Knightley returned to the red carpet in New York City on Wednesday for the premiere of her latest film, Begin Again.

As usual, Knightley got her hands on the most beautiful of designer gowns for the night and for once, she wasn't wearing Chanel Couture. Instead, she chose a midnight blue dress embroidered with a bird print from Valentino's Autumn/Winter 2014 collection.

It's hard to believe this Hollywood star, who is often kitted out in top-to-toe designer clothes, doesn't like the expensive lifestyle and was recently spotted sneaking a bottle of wine out of the pub where her husband James Righton was playing a gig.

Then again, turning up to your own film premiere in jeans and a t-shirt probably wouldn't have gone down so well...

Keira paired her Valentino design with smoky turquoise eyeshadow, a glossy curled hairstyle and Tiffany jewellery. She looked stunning - but the after-party required a change of outfit.

For her second style triumph, Keira showcased a metallic mini dress and gold heels while co-star Mark Ruffalo also embraced the blue colour theme in a three-piece suit and matching tie.

Keira's role as songwriter Greta means she sings on multiple tracks in the film. Want to hear how she sounds? Here's a preview of her singing 'Lost Stars'...

Like what you hear? Begin Again hits UK cinemas on 11th July.
