Lindsay Has Secret Half-Sis, 13, Dad Says

Lindsay Lohan may have a secret sister, if her dad is dishing the truth. Michael Lohan told OK! today that he fathered a child with another gal while separated from ex-wife Dina 13 years ago. She’s “beginning to look a lot like Linds,” Papa Lohan wrote to the girl's mom.

But he tells Extra that the teen may be no Lohan. The mother "contacted to me to say she had a paternity test done that revealed the child's father was not her husband. My lawyers are dealing with this. When we find out the truth we will deal with it in the appropriate manner." (More Lindsay Lohan stories.)
