Peter Andre has joked he's "scared" about son Junior's knowledge of the birds and the bees!
Peter, 45, explained how he'd been chatting to Junior about becoming a teenager, which led to that often awkward topic coming up...
He wrote: "I went to have 'the' conversation with him the other day and he was like, 'Hang on, Dad. Let me tell you about the birds and the bees.'

I'm scared he knows more than me, so I don't want to go there, ha ha!
"I was like, 'You know what? Forget it. I don't want to talk about this any more!' I'm scared he knows more than me, so I don't want to go there, ha ha!"
Peter added that he has given Junior one valuable piece of advice, however: to always be "respectful".
He shares son Junior with ex-wife Katie Price, 40.
The former couple also have daughter Princess, ten, while Peter shares daughter Amelia, four, and son Theo, one, with his second wife Emily.
While it's obviously a huge thing for Pete and Katie to see their son become a teenager, it's also sure to strike a chord with their fans, who watched Junior grow up on TV.
The little boy has featured in his parents' reality shows since birth, as well as appearing in photoshoots with them, and in their autobiographies.
Peter, meanwhile, previously joked he wasn't ready for either Junior or Princess to become teenagers!
He told Now magazine last year: "I drive past churches on the way to school with Princess and tell her that's where she's going to go, she's going to be a nun. She's not happy about it [laughs].
"I'm stressing about it, but I'm going to try to embrace it because every child has to go through it. Babies have mood swings, so do toddlers, so do adults, so why not teenagers?"
And in a separate interview with OK! magazine, the former I'm A Celeb contestant said he wasn't ready to deal with Junior or Princess dating as teens!

"What freaks me out is that in five years Junior will be 17 and meeting girls," he said.
"They're both still babies to me. They ask me a lot of questions which I'm dodging like bullets! But if they ask me something I don't lie to them."
Good luck, Pete!
