With news that Lindsay Lohan may have a half-sister swirling, it was only a matter of time before Ashley Kaufmann pictures (Michael Lohan’s illegitimate daughter) surfaced online.

OK! magazine and In Touch Weekly have posted pictures of 13-year-old Ashley Kaufmann, rumored to be Michael Lohan’s daughter (and therefore, Lindsay Lohan’s sister) from a four week affair he had while still married to Dina Lohan in 1994.

Michael Lohan is still awaiting the results of a DNA test to determine if he is Ashely Kaufmann’s biological father.

Ashley Kaufmann’s mother, Kristi, is claiming that Michael Lohan is the father, telling OK!, “Many times I offered to do this privately so the other Lohan kids wouldn’t be hurt. But Michael would not live up to his obligations.”
