Keira will go up against four other actresses; Patricia Arquette for Boyhood, Emma Stone for Birdman, Laura Dern for Wild, and Meryl Streep for her role in Into the Woods.

The 29-year-old wowed the crowd with her choice of gown, and proved maternity red carpet wear can be utterly chic, as the star recently confirmed she was expecting her first child with her husband, Klaxons’ musician James Righton.

Previously, Keira has been nominated once before for an Oscar for Best Actress in a Leading Role for Pride and Prejudice.
