Nick Gordon’s Death Confession!

Bobbi Kristina Brown

The violent and volatile boyfriend at the center of the homicide probe into Bobbi Kristina Brown’s mysterious death continues to REFUSE to take a lie detector test – but has secretly given authorities a stunning confession!

The National ENQUIRER has exclusively learned her hot-tempered boyfriend, Nick Gordon – who calls himself her “husband” – broke down after she passed away on July 26, but before then told police about his role in the tragedy.

A senior law enforcement source told The ENQUIRER: “He admitted to their abuse of drugs and booze, and also said they fought and argued. But Nick swore up and down that in no way did he do something that led to her death.

“He said, ‘I didn’t kill her!’”

Despite that, 26-year-old Nick, who has a criminal record, has yet to take a polygraph test, according to the police, who have stepped up their investigation into the demise of Whitney Houston’s daughter.
