It's a double whammy of exciting news.
Peter, 40, and Emily, 24, looked beyond happy in new photos for OK! magazine, which show them looking like the happiest new family we've ever seen.
Their daughter is, predictably, an absolute beauty and after cooing over her for quite a few minutes, we then clocked the MASSIVE sparkler on Emily's engagement ring finger.
Turns out that Peter, who's already dad to Junior, eight and Princess, six, proposed to Emily in their baby's nursery.
He revealed just before Christmas that he knew exactly where, when and how he was going to pop the question - and it seems that their baby's room was the most special location for the pair.
Speaking before the birth, Peter said: "For once I'm going to be a gentleman that doesn't speak. I know where, when and how it will happen and that will stay with me."
He continued: "I will do the honourable thing, not because it's the right thing to do but because we love each other and because we are just perfect for each other."
Emily revealed that she would definitely say yes, explaining: "Of course I'd say yes. I wouldn't even have to think about it. We're so happy together that if it doesn't happen tomorrow, it doesn't matter, as I know it will happen one day and it will be lovely."Peter also shared another snap from the photoshoot on his Twitter feed, causing even more cooing at omg! HQ.
This time Peter and Emily can be seen wearing matching white outfits, and their daughter looks gorgeous in a very pretty white headband.
He shared this photo on his Twitter, alongside the caption: "Introducing our beautiful baby girl to the world :)) We're feeling so blessed."
Peter admitted last week that he wasn't getting much sleep following the arrival of his daughter, because he's so excited.
He explained: "I'm not getting much sleep at the moment, but oddly, I'm not knackered. I'm just so excited."
Well we're pretty excited too now that we know a Peter/Emily wedding is on the cards.
