If this is true, this is just horrifying.
Back in June, Bobbi Kristina Brown's estate filed a $40 million lawsuit against her boyfriend Nick Gordon, alleging that he got really violent with her, and even stole money from her while she was in a coma.
But now, new legal documents describe disturbing details about what happened on January 31 — when BK was found unresponsive in her bathtub.

According to the lawyers for the late 22-year-old's estate, Nick returned home from a night of partying with booze and drugs only hours before she was discovered.
The papers say the 25-year-old got really angry after watching camera footage, and began yelling at the aspiring singer, calling her nasty names and claiming she cheated on him.
The suit goes on to say that the two argued in multiple rooms of the Georgia home before Nick gave Bobbi a "toxic cocktail" that caused her to fall unconscious.
