Lindsay Lohan has a secret half-sister, after it was revealed her father Michael fathered a daughter while he was still married to the actress’ mother Dina.
The ‘Mean Girls’ actress’ father Michael fathered a daughter while he was still married, although estranged at the date from Lindsay’s mother Dina.

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’.

The girl’s mother says that while Michael called his daughter on her 13th birthday in June and has had many conversations with her, he has never visited her or provided financial support.
She said: “It’s moment for Michael to take responsibility.”
