Katie, who has had numerous cosmetic procedures over the years, will be joined by both Junior and her daughter Princess in a special episode of ITV1's Loose Women.
And during the lunchtime debate show, Junior tells his mum: "I get how you want to have plastic surgery, but you don't need to have loads like round this area [pointing to his chest] because I think you've had too much."
The 10-year-old then adds: "And don't forget, I get you wanted to have it once because you were a model, but you don't need to have it loads of times - you're perfect how you are, mum."
The pre-recorded show, which will air on ITV1 at 12.30pm, also features the children of fellow Loose Women Andrea McLean, Nadia Sawalha and Kaye Adams.
And during the special appearance, the talk turns to marriage.
Katie was married to Junior and eight-year-old Princess' dad, Peter Andre, before their divorce in 2009. She later married and divorced cage fighter Alex Reid, and is now married to former stripper Kieran Hayler.
Putting his mum on the spot, Junior then asks his mum about her failed marriage to Peter.
He says: "You've been married three times and when you say those words, 'Yes I do..I'll be with you forever', and you say you mean it, why do you end up going, 'You know what? No no.'
"Can you tell me why you broke up with Dad? Would you like to share it with us?"
Lightening the mood, Princess then chips in: "I'm happy with you and Kieran and my dad and Emily - I like it how it is."
We can't wait to tune in!
