Casey Anthony is facing more legal drama after an inmate filed a lawsuit against her claiming to be the father of her 2-year-old daughter, Breaking Celebrity News can report.

Christopher Umberger -- who’s currently incarcerated in South Carolina  -- has filed a petition seeking a DNA test to determine if he is the dad of Caylee Anthony, whose remains were found ditched in the woods three years ago.

And while he provided no details to back up his claim, he also said he intends to sue Anthony for the death of the little girl.

The identity of Caylee's father remained a mystery throughout the explosive case.

Anthony also said that Caylee’s father had died in a car crash around the girl’s second birthday.

Anthony is due to be released from the Orlando, Florida jail on Sunday, however her legal woes are far from over.
