British actress Keira Knightley is reportedly pregnant with her first child.

Knightley is expecting her first child with husband James Righton, the co-vocalist and keyboardist for London-based band Klaxons, whom she married last year, multiple sources have confirmed to New York Post's Page Six.

The 29-year-old beauty fuelled rumors of a pregnancy as she stepped out at the Moët British Independent Spirit Awards Sunday night and appeared to stay away from alcohol. The famously svelte star appeared at her husband's side in an embroidered and billowy, ivory fur-trimmed dress very different from her usual fitted style.

Pregnancy rumours first emerged in November when Star magazine reported that she and Righton were expecting and it was a happy surprise for the couple.

"Keira and her stylist have been putting together looks that hide her growing bump," a source said.

It was announced Wednesday that her role as codebreaker Joan Clarke opposite Benedict Cumberbatch in wartime drama "The Imitation Game" had earned her a nomination for the prestigious Screen Actors Guild Awards, which are seen as an indicator for upcoming Oscar nods.
