Reports are saying that Lindsay may have a 13-year-old half sister from her father Michael Lohan.

When asked about this issue, Lindsay’s dad admitted to having an affair with a woman named Kristi Kaufmann. Now, the woman is saying that he has fathered a child from her.

Michael Lohan said that he has been in contact with the woman since last year when she contacted him and informed him that he has another daughter.

Michael Lohan has undergone a paternity test to disprove that Ashley Kaufmann, his alleged lovechild, is his true daughter. If the tests are found to be negative, he will sue Kristi with slander and defamation and if the test is proven to be true, he still won’t have anything to say to her. Michael said that Kristi came out with the news the wrong way and probably just wants money or wants her daughter to be associated with Lindsay and Ali.

With Lindsay’s new relationship, she’s probably going to be able to handle this in a mild manner and for now all we can do is wait for what she has to say.
