Chrissy went on to reveal that their baby was due in June, but over the past couple of weeks, the late-stages of pregnancy have been really taking their toll on her.
In fact, Chrissy had been taking to Twitter and Instagram to express just how much she wanted her baby to make an appearance.
Well, now the wait is over – it appears Chrissy has given birth a couple of weeks early!
She took to Twitter to share the news that she'd given birth.
And John went on to retweet the message.
The couple haven't released any further details, so it looks like we'll be waiting a little while longer to hear the baby's name or see a picture of him. So, until then, all that's left to do
is say a massive congratulations to Chrissy, John and new big sister Luna!
