They've been happily married for four years and share a two-year-old daughter.

And Keira Knightley, 32, and James Righton, 34, still looked in the first throes of love as they attended the mothers2mothers Winter Fundraiser, hosted by Salma Hayek Pinault and Francois-Henri Pinault in London on Wednesday.

The actress and the Klaxons star put on a chic display at the charity event, which is working to create a generation free from HIV.

Go Gothic like Keira in a dress by The Vampire's Wife

We've been searching for the perfect party season LBD, and Keira Knightley might just have found it!

Her midi dress is by The Vampire's Wife, and we love the luxe velvet fabric and pretty frill trim on the cuffs and hem.

Of course Keira isn't the only A-list fan of this label. Kate Moss, Sophie Dahl, Sienna Miller Daisy Lowe, Dakota Johnson, Florence Welch, Kylie Minogue, Jenna Coleman and Tilda Swinton have all been spotted in designs by Susie Cave (wife of Nick Cave - hence the brand name!) so it was only a matter of time before she got involved.

Lucky Keira got a sneak peak of a style that's not yet available, but click the link (right) to snap up an emerald green version of this dreamy dress.

Channeling Gothic-chic, Keira slipped into an ankle-skimming black gown by The Vampire's Wife, adorned with a frilled hemline and sleeves. 

Adding height to her stature with a pair of black strappy sandals, she wore her chestnut hair in loose waves, working her signature pout. 

Meanwhile James put on a suave display in a bright red suit and crisp white shirt, complete quirky bow tie as he cosied up to his belle.

Talking about motherhood to Elle magazine last year, the actress admitted the whole experience was 'astonishing', and that no job or experience in life can begin to prepare you for it.

'It's a very primal, primal love, that's quite extraordinary,' she explained. 'And the ability to have no sleep and continue going.

'It's not pleasant—I never thought that I could actually do it for the amount of time that I've done it.'
