Bobby Brown breaks down speaking about deaths of Whitney Houston and Bobbi Kristina

The R&B singer Bobby Brown broke down in tears when speaking about how his ex-wife Whitney Houston and their daughter Bobbi Kristina Brown died in similar circumstances, during an interview for ABC's show 20/20. In the interview, due to be broadcast on Tuesday, 7 July, Brown said: "The same thing that happened to my daughter is what happened to Whitney."

Kristina died in July 2015, aged 22, six months after being found unconscious in a bathtub at her home. She had been placed in a coma in the hopes that she would recover, was taken off life support. An autopsy confirmed that she had died from immersion in water and drug intoxication. It concluded that marijuana and alcohol were involved in her death, along with a sedative used to treat anxiety.

When speaking about her death, Brown said: "Krissy was and is an angel. I am completely numb at this time. My family must find a way to live with her in spirit and honour her memory. Our loss is unimaginable."

Kristina's mother, music legend Whitney Houston, was found dead in a bathtub in the Beverly Hills Hilton hotel in 2012, three years prior to her daughter's death. Houston drowned, but the effects of atherosclerotic heart disease (clogged arteries) and cocaine use also contributed to her death.

During the interview, Brown talks about his troubled relationship with Houston. When he describes the first time that he saw Houston take drugs, interviewer Robin Roberts asked "Cocaine?"

Brown simply replies, "Yes ma'am."

He later speaks about his life after divorcing Whitney in 2007: "I came into the marriage with money, and I left the marriage with nothing."

The interview will air during a special edition of ABC's show 20/20, on 7 July.
