Ashton Kutcher and Mila Kunis have shocked us all with just how open they've been about the birth of their first daughter. 

The engaged couple have a rep as being notoriously private but they've been anything but since Wyatt Isabelle came into their live. First came the announcement of their newborns name just hours after the news of the birth broke. Then Ashton revealed a photograph of his daughter along with five other babies, challenging his fans to guess which baby was their own. 

Now, the famous couple have let it slip just how they settled on Wyatt's seriously cool but rather unusual name. Unexpectedly, it wasn't their first choice... 

'We had another name picked out,' Ashton told Conan O'Brien as he made a guest appearance on the comedian's US talk show.  'We got pregnant a couple of weeks after we picked the name but when we were pregnant, the name didn't fit the energy we were feeling. One night, Mila was like, "This is not the name." I was like, "okay it's not the name."

They went back to square one, with Ashton developing a somewhat interesting way of thinking up new names. 

'I had to get the creative juices going, so we were going to a Lakers game, and I got name tourettes,' he shared. 'I just started listing off anything and everything I saw: "sign, truck, wall, door..." She [was] like, "Shut up!"  I said, "if you don't accept my bad ideas, you'll never accept the good ones." Then I was like, "I've got a really dumb idea. What about Wyatt?" She goes, "That’s it."

If you followed that then you'll know that the choice was pretty random to say the least.

Their daughter's middle name was chosen to honour Mila's heritage and her grandfather, who was Yitzhak, specifically. 

If that wasn't enough, the smitten pair have already registered their daughter's future Instagram and Twitter handles as well as her web and e-mail addresses. Ashton also revealed: 'We write her emails. One day she’ll be able to look at it and see the kinds of things people had to say.'

How sweet is that? Proof that it always pays to always be prepared. Nice work, Ashton.
