Ashton Kutcher and Mila Kunis – who is currently pregnant with their second child - are a very private celebrity couple. They secretly got married, and even though they welcomed their daughter Wyatt Isabelle Kutcher into the world in 2014 they've only posted one picture of her since.

Before she was born, they showed off their impressive nursery and they revealed Ashton was learning Russian for their child.

Cute.

We assume because Mila is funny and Ashton is hilarious that their baby will be funny too but it seems that their daughter is very cheeky – which should come as no surprise.

Ashton took to social media to reveal that his 22-month-old daughter has already swore. He posted a picture of himself no Instagram with the caption: "When your 22 month old drops an f bomb and it is (not funny) expect it's really funny and you can't laugh. #BadDads #BadMoms"

Ashton's fans saw the funny side of this too. One related to the actor and said: "At least it's not just my kids."

Another one of his followers questioned: "The question is did she use it properly like my son did around that age."

Someone wrote: "I will never forget my son at age one trying to unbuckle his car seat when we got to our destination.

"When he couldn't get it, he blurted 'Ah damn it' in perfect context. Yeah I couldn't keep a straight face either LOL."

One person commented: "Welcome to parenting."

However not everyone saw the funny side of things. One of his Instagram followers wrote: "You have to change your ways if you want to raise a child."

Someone else wrote: "So sad. That child must hear that word an awful lot."

In the past Mila spoke to Ryan Seacrest about the struggles of swearing in front of her daughter. "I try to work on it daily, and my daughter is at a place where she'll mimic the words that I saw, so it didn't really matter up until, like, two months ago when I said a certain word and she said it back."
