His ex-wife Kerry Katona was understandably angry when Brian McFadden dismissed their former marriage.
The former Westlife singer, 32, had claimed he had 'no idea what I was doing' when he married first wife Kerry - mother of his two children - in January 2002.
When Kerry, 32, posted a upset Twitter rant about how proud she was of their children, Brian declined to apologise, dismissing their five year relationship as 'shambolic'.

'I love my kids but there the best thing in my life that came from that shambolic relationship.
'Now please f**k off and let me and my wife enjoy our life. With my two girls... And to everyone else. Mind your own business.
'I'm sick of every time in my life I'm happy some pr**k tries to destroy me.'

He said: 'Vogue has made me so happy. She puts a smile on my face every day. She has made me a better person.'
