ATLANTA — Whitney Houston’s daughter has frequently declared her love for the man she calls her husband, Nick Gordon, since announcing their marriage a year ago. But a lawyer for Bobbi Kristina Brown’s father, singer Bobby Brown, says that’s not true.

“To correct earlier reports, Bobbi Kristina is not and has never been married to Nick Gordon,” says attorney Christopher Brown.

Legal authority over Bobbi Kristina’s health care and money could become a critical issue for the Houston-Brown family, which has said that Bobbi Kristina “is fighting for her life” after being found face-down in her bathtub on Saturday.
