About a dozen fans came out to the cemetery in Westfield, New Jersey, to pay their respects to Brown, 22, who died in Georgia last week six months after being found face down and unconscious in a bathtub at her home.
Holding pictures of Brown and Houston, fans crammed against police barricades as a gold-coloured hearse passed through the gates of the cemetery where Houston was buried three years ago.
Brown died after suffering irreversible brain damage in a still unexplained January incident at her Roswell home.
