A source close to Houston's relatives allegedly told TMZ that they are "heartbroken all over again" after the photos were published on the cover of the National Enquirer.
The picture was taken from inside the Wigham Funeral Home in New Jersey during Houston's closely-guarded private viewing, and family members are unable to understand how the culprit managed to get past the tight security protecting Houston's casket.
The owners of the funeral home recently came out to deny any part in the invasion of the family's privacy.
The family are reportedly making no plans to investigate any further.
