The "Imitation Game" star hit the red carpet on Saturday night at Chanel and Charles Finch's Pre-Oscar Dinner at Madeo Restaurant, where she put her growing baby bump on display in a cute black and white tiered dress.
With husband James Righton by her side, the mom-to-be proudly showed off her belly at one of her last stops before Sunday night's big awards show.
But Keira wasn't the only stylish star to be found at the event.
As the face of the brand, Kristen Stewart looked gorgeous in Chanel at the party as well, matching Keira in another black and white dress.
Other celebs in the house included Stewart's "Still Alice" costar Julianne Moore, "Mad Men" star January Jones, Jessica Chastain, Rosie Huntington-Whiteley, Tim McGraw and Faith Hill, Chris Pine, Matt Bomer and more.
