The former spouses separated in September 2004 after more than two-and-a-half years together, but in an interview published this week McFadden stated that he saw his recent wedding to DJ Vogue Williams as his "first time getting married".

Katona soon hit back at her ex's comments, tweeting that she wanted her two daughters with McFadden to know they were born into a loving relationship.
"I will never let anyone take away my first marriage not even my ex husband!" she wrote. "We may have been young but I knew full well what I was doing!!!
"And never in a million years would I ever dismiss it, especially bringing two amazing children into it...Just want my children to know there (sic) were made with love and no regrets #eyeswideopen."

She added: "Just want to say a big thank you to all the people who have walked in and OUT of my life You've all made me the person I am today.... Stronger, wiser and one hell of a great mum!!"
McFadden, however, took to the social network site later and again dismissed Katona as "some prick [who] tries to destroy me".
"Some people just can't let go of the past. Even if it destroys the future," he wrote. "I love my Kids but there (sic) 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...I'm sick of everytime in my life I'm happy some prick tries to destroy me."
