The engaged couple snuggled up in the dark for the photo, posted to Peter's Twitter account on Monday afternoon (11 August).
We can't tell from the picture where they are but we're guessing it's night and perhaps baby daughter Amelia is asleep and they're on to adult time.
"It's beaut," said the simple caption.
Peter and Emily became parents to Amelia, their first child together, in January 2014. Peter proposed to Emily shortly before the birth.
And, ever since, the 'Mysterious Girl' singer hasn't been shy about shouting from the rooftops how much Emily and Amelia mean to him.
Back in May, he gushed: "I hope Amelia takes everything after her mother. When she grows up and gets asked, 'What does your mum do and what does your dad do?' She's going to be really proud of mum."
Emily is a trainee doctor who will return to medical school this year to complete her qualification.
And although the couple are fully focused on adorable Amelia, it seems another baby may come along soon!
Speaking after Amelia's birth, Peter said: "At Christmas I'd have said no [to more babies]. Now it's yes. I've had some very dark days but our daughter has given me a new lease of life... She is gorgeous. Emily is the perfect little mum and we are all bonding very quickly."
