Keira Knightley looked like real-life royalty as she arrived at the Toronto Film Festival red carpet premiere of her new film 'The Duchess.'

Keira wore a stunning gray dress by Alexander McQueen but it was her breath taking Bvlgari earrings she wore as barrettes in her hair that added an extra twinkle to the sexy starlet. "You can't not wear sparkling things," Keira jokes.

In 'The Duchess', Keira plays the role of Georgiana, the Duchess of Devonshire, who was the distant relative to the late Princess Diana.

Keira says Georgiana would have loved the premiere! "She [Georgiana] would have been absolutely at home here."

'The Duchess' is scheduled to hit theaters on September 19th.
