She complained she looked like her gay brother after cutting off her hair and slimming down for the film.

But Anne Hathaway looked nothing short of red carpet royalty as she stepped out to the London premiere of Les Misérables on Wednesday night.

The 30-year-old actress showed off her slim shape in a glamorous pearl Givenchy gown that boasted sequin detail and off the shoulder sleeves.

The floor-length gown fell perfectly over her figure, hugging her hips before flowing out around her feet but the real drama of the dress came from the back.

The gown boasted a dipped hemline that scooped to the small of her back, leaving plenty of skin on show.

It's a tricky style to pull off but the design suits Anne's petite frame.

Anne had her elfish cropped hair styled with a sparse fringe swept across her forehead.

The star, who takes on the lead female role of Fantine in the film, lost more than 25lbs for her part in the flick but she appears to have regained her feminine shape after finishing the film.

There was certainly no lack of glamour from the girls with Amanda Seyfried, Isla Fisher and Samantha Barks all dressed to impress at the event.

Miss Seyfried also wowed in the style stakes in a Balenciaga ensemble that boasted a plunging neckline and peplum detail.

The two piece consisted of a bustier top and a ruffled asymmetrical skirt and she upped the style ante with Hollywood waves in her hair falling across her left shoulder.
