gosselin072509_23lohan.jpgMichael Lohan's ex, Erin Muller, has been arrested in Nassau County, NY for violating Lohan's order of protection.

Muller contacted Lohan by phone after the order was invoked AND admitted, on tape, that she lied to police about Michael hitting her in an attempt to have him arrested.

Lohan tells X17:
    "When she [Erin] found out she was being arrested she and her Lawyer are trying to put together a press conference to continue with her lies and try to get the press she wanted through me and my family. If a press conference is done, we will come back with our own but our will be fortified with PROOF on form of tapes, documents, emails and a lot more."


And more there is ... Lindsay's dad alleged Muller had an abortion during their relationship -- without his knowledge!
