Chelsea O'Donnell, the 17-year-old daughter of Rosie O'Donnell, is reportedly missing according to O'Donnell's website. Police have been looking for her since Sunday in the Rockland County area. She was last seen on Tuesday and she reportedly left home with her therapy dog. Chelsea was adopted by O'Donnell after allegations that biological mother Deanna Micoley signed away the child while under the influence of drugs. Since then, Micoley has fought O'Donnell over custody for her daughter. O'Donnell said Chelsea allegedly stopped unspecified medication and is in need of medical attention upon being found.
