That question about his kids Kay asked was almost certainly run past his agent a few times...
It gave him carte blanche to shed a few 'tears' and get max coverage AND get people to feel sorry for him. Kerchiing!
After the marriage Pete's management would've been desperate to wheel him out for some extra sympathy. He couldn't say he was upset over Katie, so the kids were his next best bet.
And it's worked hasn't it ?!
If you watch the K&P show closely you'd see Pete is by far and away not an innocent party. He could be v emotionally abusive and in RL is apparently not v nice either. Also he often sanctimoniously says: 'I don't want to slag off the mother of my children...' before launching into her on film and in print.
He is definitely NOT the nice guy in all this. Incredible that people can't see it.
When his 15 extra post marriage minutes are over he'll be back to being seen as the perma-tanned strumpet that he is...
