The singer took to Instagram, where he posted a photo that showed him and Emily with their faces close together, pouting at the camera.

Peter shared his selfie with Emily to Instagram
Just before Christmas, Peter surprised his fans with a revelation about his plans for expanding his family.
Writing in his column in new! magazine, the 48-year-old admitted that he was still open to having a fifth child. Peter penned: "At the start of this year I said 2021 would be the last year I would consider having more children."
The star went on: "However, as we spent a lot of time in lockdown, I think we need to put everything back 12 months! So now I'm saying if it's going to happen, 2022 is the time."

He finished by adding: "I'm 49 in February and I've always said my limit was until I turn 50, so who knows!"
If the couple do choose to have another child, it will no doubt have a magical upbringing, as the pair proved earlier this month when they sweetly invited Father Christmas himself into their home.
"Theo couldn't stop staring and asking questions! Very persistently asking where the reindeer are was the best," Emily joked on Instagram.
