A paternity test has revealed Lindsay Lohan's father has another daughter.
The Liz & Dick star's dad Michael Lohan appeared on The Trisha Goddard Show to find out whether 17-year-old Ashley Horn is the actress' half sister after giving a sample of his DNA and he now wants to get to know the teenager.
He told Radar Online: "While I am sorry this took so long, we finally have the answer, we are all okay with it and we will deal with it in the best way!"
Lohan (52) - who has four children with ex-wife Dina Lohan including his 26-year-old actress daughter and is currently expecting a baby with his 29-year-old girlfriend Kate Major - allegedly avoiding taking the test for four years.
Horn's mother Kristi pushed for the test but Horn told the show: "I don't want to be part of the Lohan trainwreck."
She also attacked Lohan for refusing to acknowledge her in the past.
She said: "What gives you the right to tell me that the kids have a right to disown me. What made you say that to me? How can you keep lying?"
