The 'Behind Closed Doors' hitmaker – who has a five-year-old son Junior and two-year-old daughter Princess Tiaamii with ex-wife Katie Price, and also helps raise her eldest child Harvey, eight – wouldn't have a problem with the youngsters pursuing a showbiz career, but only if they complete their education first.
He said: "If the kids want to follow my career path, I'd make sure they finish school first.
"I was offered a record contract at 16, but my dad made me stay on at school. That was the best thing he could have done."
Although Peter, 37, is currently single, the singer admits he hasn't ruled out having more children in future.
He told Reveal magazine: "I'm more than happy with three kids but if I meet someone special, who's to say I won't want any more in the future.
"I never thought I'd meet somebody who already had a child and I did. You can never tell what's around the corner.
"Put it this way – dating a yummy mummy isn't off the cards."
Last week, Peter – who split from Katie in May 2009 - was crowned Bounty's Celebrity Dad of the Year and was thrilled with the accolade.
He added: "It's awesome. It put the last year into perspective.
"I'll always put my kids first."
