While it may look like this mum-to-be is taking pregnancy in her stride. her recent interview on the Ellen DeGeneres show suggests that she may be panicking a little more than we realised.
Drawing the star out in classic Ellen fashion, Keira Knightley ended up admitting that she's terrified by a certain something in the newborn baby process.
Discussing the unavoidable nappy-changing rigmarole, the Imitation Game star said: "The problem with boys is, sorry, this is horrible, but when you're changing their nappies, you can get wee in your face."
Admitting that this was news to her, she continued: "I never knew that before! So, it was terrifying."
Delving further still, the 29-year-old actress revealed what she had learned about the process, saying: "Apparently they roll as well, so you have to like try to stop them while you;re trying to grab something else in order to stop them peeing in your face."
It sounds like this recent revelation has Keira yearning for a drink, admitting to the chat show that she raised the issue on a recent trip to the doctor's.
The star, who made an hilarious appearance on Jimmy Kimmel Live recently, told Ellen: "The doctor asked if I had any questions. I said, 'Yes! When can I drink? Please! I just want a margarita.'"
We're sure the Oscars ceremony this weekend will take Keira's mind off nappies for an hour or two!
