The 22-year-old daughter of Whitney Houston and Bobby Brown was found unresponsive in her bathtub in January 2015, passing away almost six months later, and her fiancé Nick insists he was in no way responsible.

He told The Sun on Sunday: "What happened to Krissy was Krissy's own doing, sad as it is."

Whitney died in 2012 aged 48 from accidental drowning in a bath at the Beverly Hilton hotel, though drug use was a contributing factor in her ill-health and Nick claims Kristina went into a downward spiral after her mother's death.

He said: "Krissy suffered anxiety attacks. We became terrified of the bath, I didn't even like deep water.

"She would drink wine bottle after bottle.

"She'd drink to blot out the pain and it always got worse near the anniversary of Whitney's death and her birthday in August."

Despite the claims of Bobbi Kristina's family that he played a part in her death, Nick insists he still doesn't exactly know what happened as he had been out with a friend earlier in the evening on the night she died.

He said: "Krissy was far gone when I got home. I saw two empty bottles of wine and I don't know what she mixed with the wine.

"Later I heard the scream and ran upstairs. Max [Lomas, a friend of the couple] had got Krissy out and she was on the floor.

"I told him to call paramedics and I started CPR. Then the police arrived and Krissy was taken to hospital."
