"Imitation Game" actress Keira Knightley has reportedly welcomed her first baby with husband James Righton. 

According to Channel 24, the "Pride & Prejudice" actress has given birth to a baby girl.

Knightley had spoken at many talk shows about being pregnant during the awards season, and had also joked about how she completely unprepared she was for the baby.

When talk show host Jimmy Kimmel asked her if she has prepared the room for baby's crib, she replied, "No. They're quite small though right?... Do they need a room of their own?"

In "Ellen", Knightley said that since keeping the baby inside of her is not an option, her plan is to "get it out". "But apparently there's more to the plan than that. I don't know what that is. Still, my plan is to get it out. It will come out," said the "Pirates of the Caribbean" star.

Knightley has always been quite private and protective about her personal life. She has also been reluctant about publicising her life via any social networking site.

Therefore, the news of the baby's birth was also not widely reported. Other than the fact that the baby has "come out", no specific details about the baby, including the date and time of birth, has been revealed.
