It looks as though
The Golden Globe nominee -- for supporting actress, "The Imitation Game" -- is about 12 weeks along, multiple sources told Page Six, which first had the news.
She avoided free-flowing Champagne at the British Independent Film Awards in London on Sunday, Us Weekly reported in its pregnancy confirmation.
Speculation that Knightley might have a baby on board ramped up when the lithe actress wore looser dresses on a couple of red carpets, Gossip Cop noted.
Though the 29-year-old's dress for the event had enough room around the waist and hips to hide a small secret, an onlooker would have to work pretty hard to discern any sort of baby bump in myriad pictures from the red carpet.
Knightley and musician James Righton, 31, got married in May 2013 following a yearlong engagement. About a dozen friends and family reportedly attended the casual, low-key ceremony at a town hall in the south of France.
A Knightley rep did not respond Thursday to a Los Angeles Times request for comment or confirmation.
