In his first interview since the tragic death of his daughter Bobbi Kristina, Bobby Brown revealed new details about his tumultuous marriage with Whitney Houston.
According to his upcoming memoir, Every Little Step, the R&B star first saw his then-wife doing drugs before their wedding ceremony, describing her as "hunched over a bureau snorting a line of coke."
"Shocked" to see Houston in such a state, Brown says he declined to partake when Whitney offered him a hit.
"She wasn't that," Brown tearfully told Robin Roberts in a preview clip from Tuesday episode of 20/20. "The drugs wasn't her. She did drugs but drugs didn't do her. She knew how to handle herself. It only made me love and want to protect her more."
Brown also denied "leading" Whitney into serious drug use.
"It wasn't me who started her," he insisted. "I take my part and I take it hard for me even being a part of it, but we all have our own minds and some of us are stronger than others."
Later, the 47-year-old discussed the tragic loss of his daughter, Bobbi Kristina, who was discovered unresponsive in the bathtub of her home last year.
"The hardest thing I've done in my life was tell my daughter to let go," the sobbing singer told Roberts. "My baby's gone!"
He also acknowledged the eery similarities between the sudden deaths of Bobbi Kristina and Houston, who was discovered dead in a hotel bathtub on February 11, 2012 at 48.
"The same thing that happened to my daughter is what happened to Whitney," he admitted to Roberts.

As Radar extensively reported, Bobbi Kristina's boyfriend, Nick Gordon, and a friend found her face-down in her bathtub on January 31, 2015. She died after six months in a coma that summer.
According to the autopsy report, the 22-year-old succumbed to immersion and water and mixed drug intoxication. (Like her daughter's sad case, drugs also contributed to Houston's death, a coroner's report revealed.)
Bobbi Kristina's estate later sued Gordon for wrongful death, claiming he beat her and injected her with a "toxic mixture" just before her near-drowning. He has insisted he is innocent of any crime.
Brown's full 20/20 interview will air June 7 at 10 p.m. EST on ABC.
