Gordon, who has completed rehab since his first tumultuous interview with Dr. Phil in March 2015, also spoke about rumors regarding Brown's drug use during their relationship.

Gordon admits to have used drugs with Brown "socially" while her mother was still alive, but revealed that Brown's drug use "got really bad" after Houston died: "At the time, that's kind of the only way we knew how to deal with what had happened."

ET's Kevin Frazier sat down with Dr. Phil days before the two-part special airs on April 28 and 29, where he revealed he didn’t let Gordon off easy during their sit-down.

"I ask him straight up, 'Did you murder Bobbi Kristina? Did you concoct a lethal cocktail that you gave her to end her life?'" he revealed on Tuesday. "There are accusations from this family that he in fact was involved in the death of Whitney and I ask him straight up, 'Did you murder Whitney Houston?'"

"We're going to hear the answers and people are going to be able to judge for themselves the credibility of his answers and explanations," Dr. Phil added.
