The singer shared a candid video of doctor Emily helping Junior out by removing his blackheads using her tools, after the 15-year-old had tried to treat them with a nose strip.
"Now Emily is doing nose surgery on J. This house is weird :))," Peter captioned the candid video.

Fans quickly reacted to the clip, with one writing: "What an incredibly lovely wife you have... so fabulous to see the relationship between her & your children."
Another added: "Love their bond!" while a further follower commented: "Emily is literally the best step mum... hands down."
Emily recently received her COVID vaccination
NHS doctor Emily now has her own Instagram account, launched in October 2020, where she shares some rare snippets of the couple's children - as well as raising awareness for the causes she is passionate about.
The couple contracted coronavirus in January, and detailed their experiences in an interview on Good Morning Britain. Emily later received her vaccine, and recently paid tribute to the hard-working NHS staff working to give out the injection.
She thanked NHS workers for their hard work rolling out the vaccine
"Nearly 2 weeks on from my vaccine and just reflecting on the amazing work of thousands of people who have come together to make this vaccine programme such a success," she wrote on Instagram.
"Thank you again to the lovely Laura at Epsom Hospital, she is a paediatric nurse who is working extra shifts in the vaccine clinic on top of her already busy job and a family to care for. What a star! Thank you to everyone who is going above and beyond to care for us all... #nhsheroes." Add the following script only if it's not already included in your site
