Ford, 26, is best known for her hit single "I Wanna Be Bad," from her 2001 album, "Willa Was Here." Like Smith, she was a Playboy model.
Smith, 39, died in February from a mix of prescription drugs, leaving behind a baby daughter and a possible fortune from her marriage to the late J. Howard Marshall II, the Texas oil tycoon. A court in the Bahamas announced Tuesday that DNA tests proved former boyfriend Larry Birkhead was the baby's father.
A call by The Associated Press to a representative for Ford wasn't immediately returned Wednesday.
Ford, whose real name is Amanda Lee Williford, appeared as a "celebrity dancer" last year on ABC's "Dancing With the Stars" and has hosted several reality television shows.
