Nearly a year after burying his troubled daughter, Bobby Brown is finally opening up about Bobbi Kristina's tragic passing.
"The hardest thing I've done in my life was tell my daughter to let go," the sobbing singer tells reporter Robin Roberts in a preview clip from Tuesday's episode of 20/20.
"My baby's gone!"
He then acknowledges the eery similarities between the sudden deaths of Bobbi Kristina and his ex-wife, music icon Whitney 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 admits to Roberts.
As Radar extensively reported, Bobbi Kristina's boyfriend, Nick Gordon, and a friend found her unresponsive body in a 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.)
In his upcoming memoir, Every Little Step: My Story, Brown also shares his theory that a car crash may have contributed to his daughter's demise, Radar revealed earlier this week.
"We asked the doctors whether she could have suffered some type of brain trauma or hemorrhage that didn't present itself until four days later, resulting in the bathtub incident," he writes. "But the doctors couldn't really give us definitive answers."
Brown's 20/20 interview will air June 7 at 10 pm est on ABC.
