He was just speaking from the heart when he called his ex-wife a "pig faced mole!"
"I was so infuriated when I read it and it was so typical. I just lost it and (went) straight on Twitter. You know probably the things I said, if I had've sat down and thought about it and spoke to a journalist about it, I wouldn't have said it.
"But at the end of the day I spoke from the heart. I was angry and I got my point across. I might have been a bit over-the-top, but at least I got my point across and I got to vent."
McFadden has lost two custody battles in England for his two daughters Molly and Lilly, but he hopes they may eventually want to move down to Australia where he lives with fiancee Delta Goodrem:
"Molly's nine in August and Lilly's now seven, so there's only a few more years until they can pretty much do what they want. I would like to bring them to Australia one day and I know they want to come."
As for what he thinks of Kerry, he's made it pretty clear and says, "I don't know her anymore and I don't know what goes through her mind."
Neither do we!
