Michael Lohan told the press before he told Lindsay that he has another daughter. Ok not really, but he did tell the mag that some lady he hooked up with while he was separated from Dina had a kid that she claimed was his. Michael tells 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." Apparently this secret daughter "is beginning to look a lot like Linds, with a mix of [younger brother] Cody, believe it or not." The kid is now apparently 13 years old. Scandalious!!
