WFTV has learned that Casey Anthony has been subpoenaed to appear in court in connection with her defamation trial in January.

Cheney Mason, one of the lawyers who defended Anthony against murder charges, accepted the subpoena for her to show up at the civil trial.

Last week, a judge ruled that Anthony had to release her address or have one of her attorneys accept the subpoena for her. Mason accepted the subpoena to prevent Anthony’s address from being released.

Zenaida Gonzalez is suing, claiming Anthony ruined her life when she said a baby sitter by the same name kidnapped Anthony’s daughter, Caylee.

Investigators tracked Gonzalez down, because her name was on a visitor's card at the Sawgrass Apartments where Anthony said she dropped Caylee off with the nanny.

Gonzalez said once that happened, people have treated her differently, and she wants at the very least an apology from Anthony.

Anthony's lawyer told WFTV that she may apologize to Gonzalez.

Anthony's lawyer said the nanny Anthony named was "Zenaida Fernandez Gonzalez," and that's not the plaintiff's name. They also argued to Circuit Judge Lisa Munyon that Anthony has already admitted that the nanny doesn't exist.

Caylee's body was found behind Anthony's parents' home on Suburban Drive.
