Looking gorgeous on the arms of their hubbies James Righton and Benedict Cumberbatch, both ladies opted for totally different looks for the 87th Academy Awards on Sunday evening (22 February).
But both killed it!
Held at the Dolby Theatre in Los Angeles, California and hosted by Neil Patrick Harris, Keira, James, Benedict and Sophie joined many fellow Brits at this year's Oscars including Eddie Redmayne, Sienna Miller, Rosamund Pike and Felicity Jones.
Keira was nominated for Best Supporting Actress for The Imitation Game, but missed out (yet again) to Patricia Arquette for her role in Boyhood.
She still radiated her way through the ceremony, however, in a stunning, nude Valentino dress which featured delicate, floral embroidery and French phrases.
Her hair was left loose and wavy, held back with a simple flower headband and her make-up was also kept very natural, giving her whole look a kind of ethereal feel.
In complete contrast, Benedict Cumberbatch's new wife, Sophie Hunter went for a much more streamlined and sexy look in a one-shouldered, Lanvin number that showed off a lot of leg and made her skin look positively glowing.
Who'd have even known Sophie was four months pregnant in this stunner of a gown?!
Sophie complemented her dress with gold accessories, red lips and a sleek updo that couldn't have been more different to Keira's softer, slightly angelic look.
But who looked the best? We just can't decide...
And Benedict, you might have missed out on your first ever golden statue, but you scrubbed up very nicely in your white tux, too!
