And now new mum Chrissy has taken to her Instagram to share the first picture of their adorable daughter, who they named Luna. She captioned the sweet snap: 'hi my lulu!'
Messages from her 6.2 million Instagram followers have been flooding in on the post. One follower commented: 'You'll probably never read this, but that's exactly what I was naming my daughter!! That's so strange! Congratulations! You're going to be such a great mama!' while another added: 'no other love liken that of a mommy and baby'.
The couple, who've been married for over two years, first announced Luna's arrival on their social media accounts, and it's fair to say they couldn't wait to share the news!
Chrissy, who rose to fame as a Sports Illustrated model, shared a picture of her newborn's weight on Instagram and revealed the name they'd chosen for their baby girl.
The 30 year old wrote: 'She's here! Luna Simone Stephens, we are so in love with you! And sleepy. Very sleepy.'
Husband John, 37, quickly followed suit, tweeting: 'Our new love is here! Luna Simone Stephens, born on Thursday, the 14th. We couldn't be happier!'

Chrissy later joked that her hubby was doing well following the birth, telling fans: 'to everyone asking, john is healing perfectly'

Chrissy has been outspoken about her pregnancy since announcing she was expecting back in October. At the time, she took to her Instagram to announce the happy news, saying: 'John and I are so happy to announce that we are pregnant :) As many of you know, we've been trying to have a baby for a while now. It hasn't been easy, but we kept trying because we can't wait to bring our first child into the world and grow our family,' she wrote.
'We're so excited that it's finally happening. Thank you for all your love and well wishes. I look forward to all the belly touching! Xx'
Chrissy has spoken out about her and her husband's struggle to conceive, which she opened up about during an appearance for the Television Critics Association summer press tour last year.
'I will say, honestly, John and I are having trouble,' she confessed. 'We would have kids five, six years ago if it'd happened,' she added. 'But my gosh, it's been a process!
'So, anytime somebody asks me if I'm going to have kids, I'm like, "One day, you're going to ask that to the wrong girl who's really struggling, and it's going to be really hurtful to them. And I hate that. So, I hate it. Stop asking me!"'
Chrissy and John conceived their baby through IVF, even hand picking the embryo right down to their baby's gender - a move which caused controversy amongst their fans at the time. 'I've made this decision...Not only am I having a girl, I picked the girl from her little embryo. I picked her and was like, "Let's put in the girl,"' she told People magazine.
One fan wrote on Twitter: 'I do think it's sad people would pick a specific gender / prefer a specific gender.' But the model was quick to shut down any criticism, tweeting: 'What year is this!? And for the record, I am always happy and open to speak on infertility. The more casual, the better! I don't mind.' Congratulations to the new family - lovely news!
