Speaking about the relationship by 13 years ago, Michael - who has three other children, Michael, Ali and Cody, with Dina - told America’s OK! magazine: “Years later the woman contacted me, convincing me that I was the only person she was with and that she had my child.”
Michael - who married

Dina in 1985 before they divorced in 2007 - has even written letters to the girl’s mother saying his illegitimate daughter “is beginning to look a lot like Linds, with a mix of Cody, believe it or not”.
He plus sent his daughter a photograph of himself, which he signed ‘Love Daddy’.
