It has been just over two months since news broke that Keira Knightley is pregnant with her and husband, musician James Righton, first child together, and the British star is already showing concerns of having a baby boy.

While appearing on The Ellen DeGeneres Show on Tuesday (Feb 17th) the pregnant Oscar nominee opened up about preparing to be a mother for the first time, and her fear of changing diapers if her child is male.

"Somebody said to me the other day, the problem with boys is - sorry, this is horrible - but when you're changing their nappies, you can get the wee in your face...I never knew that before, so it was terrifying," she told the host, who replied, "That doesn't seem fun."

"No," Knightley quipped. "And apparently they roll as well, so you have to try to stop them while you're trying to grab something else in order to stop them peeing in your face. So that sounds quite interesting."

Although the 'Imitation Game' actress and her hubby haven't learned the sex of their baby, Knightley is definitely aware of her plan of action when the time comes to give birth.

"Sorry, but what is the plan apart from to get it out?" she said. "There isn't an option to keep it in, is there? So, I'm assuming my 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."

During this year's movie awards season, Knightley has constantly had Righton by her side, but this may be because he is also benefiting from his wife's pregnancy. "My husband's having a great time. I'm eating for two and he's drinking for two," she revealed. "There's a lot of free champagne, so he thinks because I'm not drinking the free champagne, he has to. So, all of it."
