LOL @ TsarChasm! "Is it a fashion thing or was he just a bit rubbish making packed lunches? "
I don't think MJ lied (re: kids' conceptions and surgery) I suspect he presented the truth in a slightly different and pedantic way. Unfortunately, I missed this interview this time round, but as I recall, MJ said his children were a 'gift' from Debbie and were a 'natural conception' "Oh really?" I thought, as I'd recently heard of the GIFT technique (Gamete Intrafallopian Transfer), and yes, it is a natural conception.
Similarly, when MJ is asked about surgery, he claims two necessary surgeries (he had genuinely broken his nose) - possibly (in his own mind) he labelled the other work he had done as 'cosmetic procedures' rather than 'surgery', and Bashir never mentioned any of those.
Well, OK that's just conjecture about the surgery thing, but I'm pretty certain my memory serves me well WRT Debbie's 'gift'. His description of Paris' birth would surely tell you that this lady was a surrogate. But they are certainly 'his' children, I have no doubt that he loved them as much as any parent (natural or adoptive) loves their child, despite the baby dangling and other misguided notions.
