Lindsay Lohan has two brothers and one sister, Ali ... well, turns out that she has two sisters!
Lilo has a secret 13-year-old sister that no one really knew about! Naughty Michael Lohan!
Lilo's dad, Michael, has admitted to OK! Magazine that back in 1995 he had a relationship with another woman which resulted in a pregnancy. He wasn't yet divorced from Dina Lohan, but they were separated.
Michael also tells Extra: "I met Christie -the mother of the reported love-child- in 1982 in Houston. In 1995, when I was separated from Dina, she contacted me that she was moving to Long Island… I was with her for a week. Years later, while I was in prison, she contacted to me to say she had a paternity test done that revealed the child’s father was not her husband. She said I was the only other man she had been with".

The woman has already talked to the media and has said that Mike has to take responsibility for his actions!
News on the street has it that he did in fact contact his daughter and has been calling her.

I guess soon he's going to have to take financial responsibility as well! Ouch! That's gotta hurt!
