Nick Gordon, who was the partner of Whitney Houston's late daughter Bobbi Kristina Brown, has lost a wrongful death lawsuit filed by her estate.
Brown, 22, died in July 2015, six months after being found unresponsive in a bath by Gordon and a friend at her home in Atlanta.
An autopsy found drug intoxication and the immersion of her face in the water contributed to her death.
A judge in Georgia ruled Gordon legally responsible by default after neither he or his lawyer attended a hearing on Friday. It was his second missed court date.
The multi-million lawsuit
The lawsuit alleged that Brown, who was Houston's only daughter with R&B singer Bobby Brown, has been given a "toxic" drugs mixture by her boyfriend.
It also included claims that she had been physically abused by Gordon and that he took money from her estate without her permission.
The lawsuit, which was filed in August 2015, sought $50m (£38m) in damages. The original claim was for $10m but it was updated.
Gordon had denied the allegations and said he tried to save his girlfriend's life.
Gordon, who has not been criminally charged, can appeal the judges ruling but if he loses a jury will determine how much he should pay.
