Keira Knightley Breaks Silence On Her Pregnancy

— -- For weeks, reports have stated that Keira Knightley is expecting her first child with husband James Righton.

However, the SAG Award nominee hadn't said anything about them until Sunday night, when it came up during a discussion about her stilettos.

"I can kinda go, 'Well, I’m pregnant so my shoes have to come off,’ and nobody is allowed to say anything!" the "Imitation Game" star told E! News, according to People magazine. "So that's quite nice."

Knightley, 29, wore a Erdem gown to the awards show, concealing her growing bump. The fashion choice was a necessity, she said.

"[My] waist has disappeared!" she said. "[But] for a very good reason."

This is the actress' first child. She married Righton, a rocker, in 2013.
