The Mysterious Girl singer has shared a clip of him dancing alongside his two kids with Katie Price, Junior and Princess - and it's ADORABLE.
While Pete mimes along, Junior shows off his moves to Mark Ronson's Uptown Funk while they're parked up in the car.
Meanwhile Katie's mini-me Princess joins in the fun and can be spotted miming along and showing off her performing abilities from the back seat.
Ever cautious, Pete captioned the clip, "Nutters :) Before you say anything, we were parked up."
The reality TV star also has a two-year-old daughter Amelia with wife Emily MacDonagh, and she's expecting another baby too.
He's sure to provide endless fun to the next addition to the family, who is due at the end of the year.
However the couple are yet to discover the sex of the baby.
Speaking to OK! magazine, Pete admitted, "I'll be so happy if we have a girl, but I'll be even more buzzing if it's a boy.
"Junior is my best mate so it would be nice to have another little boy to be pals with, especially as Junior is only with me half the week."
