She's gone from grungy tomboy to glamorous star in the past year, and now Kristen Stewart's stunning style transformation is getting recognized in a big way.

The Twilight actress was just voted best dressed by Glamour UK over several fashion-forward celebs including Emma Watson, Victoria Beckham, Blake Lively and even Kate Middleton.

And the British magazine was equally kind to K-Stew's boyfriend, naming Robert Pattison, 25, the best dressed man in Hollywood in addition to putting the duo at the top of its best dressed couples list.

The co-stars and real-life loves will have a chance to show off their sartorial skills when they hit the Cannes Film Festival red carpet next month.

Stewart, 22, who has three films coming out in 2012 (On the Road, Snow White and the Huntsman and The Twilight Saga: Breaking Dawn – Part 2), recently landed her first high profile fashion gig as the face of the newest Balenciaga fragrance for women.
