An amendment to the suit, filed in Fulton County Superior Court, levels damning new allegations against Gordon. A statement from his lawyers calls the suit "slanderous and meritless."
No criminal charges have been filed in the case.

Bobbi Kristina was buried next to her mother, the late Whitney Houston, after memorial services here and in New Jersey. Nick did not attend but his mother issued a statement at the time saying he was devastated.
Bobbi Kristina death at age 22 on July 26, following months of hospitalization. An initial autopsy showed no obvious cause of death.
The suit claims that Bobbi Kristina, who often referred to Nick as her “husband” had a tempestuous argument with him on Jan. 31 “after (Gordon) returned from being out all night on a cocaine and drinking binge.”
The suit claims he “gave Bobbi Kristina a toxic cocktail rendering her unconscious and then put her face-down in a tub of cold water causing her to suffer brain damage. (Gordon) then came out of the master bedroom wearing a different set of clothing than he was in prior to his argument with Bobbi Kristina. Afterward he got in bed, and laid his head on female guest’s ankle and stated, “Now I want a pretty little white girl like you.”
The suit goes on to claim that 15 minutes after this allegedly happened, Gordon let the water out of the tub, and tried reviving Bobbi Kristina, saying “wake up” as he performed CPR.
The suit claims that “(Gordon)’s violent attack on Bobbi Kristina and associated reckless and toxic cocktail caused her to sustain a profound brain injury, which ultimately caused her death.”
The lawsuit does not specify what was in the so-called “toxic cocktail” or identify the "female guest" or any sources of information who provided the basis for the suit. It goes on to repeat past claims that Gordon took money from Bobbi Kristina’s account while she was incapacitated, without authorization.
Bobbi Kristina's conservator, Atlanta attorney Bedelia Hargrove, added this comment to her amended filing:
