The 15-year-old previously had to isolate for two weeks in November after a classmate of his had tested positive for coronavirus.
Peter, 48, who shares Junior and his 13-year-old sister Princess with ex Katie Price, appeared to be in high spirits despite the family being stuck in the house.
Princess shared a video of him cleaning the kitchen with all his usual enthusiasm and energy while singing My Humps by the Black Eyed Peas.
Making the song more relevant to his activity, Peter changed the lyrics to sing: ‘My lunch. My lunch, my lunch, my lunch. My lovely lady lunch,’ as he wiped the surfaces down.
While Pete was into the song, Princess was less taken with it as she joked: ‘Why is my dad so weird, someone help.’
Emily also revealed that the kids had been spending time in the garden too, as she revealed the flowers Theo had picked for her.
She wrote: ‘Theo picked these for me today, he calls them Don’t Forget Me instead of Forget Me Not! So gorgeous.’
