Isla Fisher in daring plunging gown at Les Misérables world premiere in London

Isla Fisher stole the show from her husband Sacha Baron Cohen in daring plunging white gown by Willow with triangular cut out panels which accentuated her slim figure and red hair at the London premiere of Les Misérables.

But it must have got a little chilly as the pair posed up and ever the gentleman, Sacha Baron Cohen offered his wife a chivalric hand and helped her into her black jacket.

Although all eyes may have been on Isla Fisher, 36, her 6ft 2in husband perhaps had the best view of her daring satin gown as she shone on the red carpet.

Sacha Baron Cohen, who plays Monsieur Thénardier alongside Helena Bonham Carter, did his best to look dashing next to his stunning wife.

There was a general theme of innocence as star of the show Anne Hathaway wore 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.

Sacha Baron Cohen’s onscreen wife Helena Bonham Carter , who plays Madame Thénardier, looked just as quirky as usual in a black gown.

Isla Fisher recently said being “Mrs. Borat” can be rather embarrassing.

“I cannot tell you how embarrassing he is in social situations,” Isla Fisher said.

“To him, there’s no difference between the awkward gaffes he deliberately makes as a comic, and the terrible faux pas he innocently commits as my husband.”
