Oscars 2015: Pregnant Keira Knightley Glows On The Red Carpet Ahead Of The Academy Awards (PICS)

Keira Knightley

Keira is nominated for the Best Supporting Actress accolade and she's been busy promoting 'The Imitation Game' in the US, with her co-star Benedict Cumberbatch in recent weeks.

The 'Sherlock' star could also pick up an Oscar - if he can beat his long-term pal and fellow Brit actor Eddie Redmayne, that is.

Will Keira bag an award?

Keira's category is a particularly tough one, and she's up against stars including 'Boyhood' actress Patricia Arquette, and the one-and-only Meryl Streep, for her role in 'Into The Woods'.
