Nick Gordon is talking about the deaths of Whitney Houston and Bobbi Kristina Brown.

Brown, the 22-year-old daughter of Houston, died in July 2015. She never regained consciousness after being found unresponsive in the tub of her Roswell home in January 2015.

In 2012, Houston drowned in a bathtub. An autopsy report indicates that cocktail of drugs were in her system.

The first part of the interview is a review of that much-talked-about interview given several months ago. Gordon, the former boyfriend of Bobbi Kristina Brown, now admits he was under the influence when he spoke to Dr. Phil the first time.

After leaving the set headed for rehab, Gordon punched a Dr. Phil staffer. He admitted to using alcohol and Xanax at the time.

Gordon told Dr. Phil that he first moved in with the late Whitney Houston and her daughter because the two “were lonely” after Whitney’s divorce with singer Bobby Brown.

Gordon said that if Whitney used drugs in the home, she kept it to herself. A skeptical Dr. Phil then referenced an infamous Houston interview in which she said “crack is whack” and admitted using other drugs. Gordon was living with Houston at the time.

The interview then moved on to the night that Houston died. Gordon said he heard screams from her dressing room and, as he moved closer, he realized that it was Whitney's hair dresser who was screaming. Gordon said he ultimately was the one to tell Bobbi Kristina that her mother had died. He says that’s when drug use got the best of him and Bobbi Kristina.

“It got really bad after Whitney passed; it was the only way we knew how to handle what was happening,” Gordon said.

Gordon said the two took pain pills and smoked.

“She would get something numb the pain,” Gordon said.

A civil lawsuit filed by Bobbi Kristina's conservator last August accused Gordon of assault, battery, intentional infliction of emotional distress, and transferring money from her account into his own without authorization. Gordon has denied responsibility.

The second part of the interview airs Friday on 11Alive. In it, Gordon opens up about the downward spiral he and Bobbi Kristina took together and answers tough questions about his involvement the night she died.
