Lindsay Tells Lawyer: Muzzle My Dad!

Lindsay Lohan has now asked her lawyer to take legal action against her dad, stat.

We've learned Lindsay contacted her lawyer, Shawn Chapman Holley, yesterday, asking her to get a restraining order against Michael Lohan, who has been selling his daughter out on TV, talking about her alleged drug use.

Chapman Holley tells TMZ she's putting together a case against Michael and will decide which legal move makes the most sense. Aside from getting a restraining order, Chapman Holley could file a defamation lawsuit against Michael on Lindsay's behalf.

Chapman Holley is also getting in touch with authorities in New York, trying to find out if Michael may have violated a criminal protective order.
