Keira Knightley and Sienna Miller

Sienna Miller and Keira Knightley teamed up at the British Independent Film Awards in London on Sunday.

The Edge of Love co-stars Keira, 23, and Sienna, 26, proved a real double act at the London movie event. They held hands as they escorted one another down the red carpet at the British Independent Film Awards at the Old Billingsgate.

The ladies star in the film 'Edge of Love' where they portray women who are both involved with legendary poet Dylan Thomas.

In a high-necked gothic lace gown, Keira could have stepped right off the set of one of her period dramas. She kept the look modern though by teaming her dress with classic black satin courts and leaving her locks loose, with a side-swept fringe.

Keira is seriously the most exquisite woman in the entire world

Onto Sienna, and she chose a little black dress with a twist. With bejewelled shoulders and sequin detailing, the chic number was a stylish choice.
