Bobbi Kristina Brown allegedly did crack and smoked heroin.
For the second time, Gordon has faced such accusations. The alleges have been made in response to Gordon's filing of motion to stay discovery in a civil lawsuit he faces.
Brandi Burnside said Whitney Houston's 22-year-old daughter did respond to emotional cues. In related reports, Gordon has inadvertently spurred rumors of murdering Bobbi Kristina Brown.
Gordon admitted he had argued with the 22-year-old after reviewing video footage just hours before Bobbi Kristina was found unconscious in a bathtub.
Brown accused Gordon of murdering her niece while she also claimed Whitney Houston was murdered. The state of cause of Houston's death in 2012 was drug overdose.
Gordon's response to a lawsuit filed before the court admits he had an argument on the day Bobbi Kristina was found unconscious but denied wrongful death accusation.
Brown wrote in a Facebook post earlier this month that Whitney Houston wanted her to be Bobbi Kristina Brown's guardian.
Fulton County Medical Examiner's Office did not find any obvious signs of injuries that could have contributed to Bobbi Krsitina Brown's death.
