The reality TV star - who has two children, Junior, seven, and Princess Tiaamii, five, with the glamour model - admits he avoids discussions about his former spouse's impending arrival with new husband Kieran Hayler.
He said: ''I'm very good at diverting, so there haven't really been any long conversations about it.''
The 40-year-old star is currently locked in a bitter lawsuit with Katie, 35, who is suing him and former manager Claire Powell for allegedly launching a smear campaign against her.
However, despite their parents' differences, Peter reveals his children are blossoming - and cheeky Junior, who loves to be the centre of attention, even takes after his father.
He said: ''He definitely reminds me of myself at that age. I was always in trouble with my mum and dad for showing off and I'd always be doing the kind of stuff he's been doing. But my parents were a lot stricter.''
The cute tot is also a hit with the ladies, it seems, much like his father.
He added in an interview with new! magazine: ''He says he's got seven girlfriends, but I'm like, 'No, you've got seven friends who are girls. There's a big difference.' But he says, 'No, dad, I've got seven girlfriends.' ''
