It was recently revealed that Lindsay Lohan has a half-sister.
Her father Michael replied when asked if it was true that he had fathered a daughter when he was still married, although estranged at the time from Lindsay's mother Dina, "Years later the woman contacted me, convincing me that I was the only person she was with and that she had my child".
Michael and Dina were married in 1985 and divorced in 2007 and he has apparently 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 also sent his daughter a photograph of himself which he signed 'Love Daddy'.
The girl's mother says that although Michael did call his daughter on her 13th birthday in June and has had many conversations with her he had never visited her or provided any financial support.
She added, "It's time for Michael to take responsibility".
