Keira Knightley 12 weeks pregnant?

Keira Knightley may be 12 weeks pregnant with her first child.

The 29-year-old actress has not yet commented on whether or not she and her husband, 31-year-old Klaxons musician James Righton, are expecting a baby. But the cat was let out of the bag by a 'family source' who spoke to an American magazine.

"Keira and James are thrilled," the source told Star. "This wasn't planned, but that is how they wanted it."

The source added that Keira is around 12 weeks pregnant and she has called on the help of her stylist to put together outfits that hide her growing baby bump.

So far this seems to have consisted of a lot of ruffled dresses and dungarees - the one item of clothing that positively screams maternity wear!

Keira added to the growing speculation by drinking nothing stronger than water while out in New York on Monday evening (October 17) to promote her new movie Imitation Game, in which she stars alongside Benedict Cumberbatch.

Keira explained that her abstinence was due to an early alarm call the next morning as she was appearing on TV show Good Morning America, but her protestations have done little to stem the speculation.

"It's one way to ruin a party," Keira told the New York Times. "When they go, 'You have to get up at 5:30 in the morning the next day.'

"There are some really bad stories about people doing that and then going on these shows," she said, while pointing to her glass of water. "You don't know what could come out of your mouth after a night out."
