Lindsay Lohan and her mother Dina are suing Fox News Channel and Sean Hannity for defamation, saying that the network has implied that they do cocaine together.

As first reported by TMZ, the lawsuit cites comments made by Michelle Fields about a year ago after Philip Seymour Hoffman's death from a heroin overdose. "Lindsay Lohan's mom is doing cocaine with her," Fields said.

The suit says Fields' comments were "a direct smear on the character/reputation of Lindsay and Dina" and "malicious innuendo," because they implied that she may also die of a drug overdose.

Fox News has issued a statement in response. "We will defend this case to the fullest," the network said. "The remark about which Lindsay and Dina Lohan complain was made on live television by a guest nearly a year ago. We removed the segment from our archives altogether last February and also apologized on-air. At that time, the Lohans did not make any demands for money, and we are surprised they are doing so now."

Fields' remarks came in the wake of a recorded phone call that Lindsay made to her father Michael in 2012, in which she said her mom was on cocaine.
