Gordon has denied claims in a civil lawsuit that he injected his fiance with a “toxic cocktail” of drugs and placed her in the bathtub.

Brown was found unresponsive in a bathtub on January 31 last year and died six months later.

“I went out with a couple of buddies of mine earlier that day and we were out having a good time. Krissy thought I was with some other females and that’s when she got upset. She called and said I had to come home,” Gordon told the Daily Mail.

He says he got home about 4am.

“I saw a couple of bottles of wine. I thought she had just been drinking, maybe smoked a little. She was upset, we got into a little argument and then we made up and went upstairs and lay on the bed for about 45 minutes and did what adults do,” he said.

Gordon says afterwards he went to play his PlayStation while Brown was “doing her own thing”.

He said it was only when the cable guy came that his friend Max, who was escorting him through the house, found her in the bathtub.

“I knew instantly something was wrong. You know there’s a tone; you can hear it in someone’s voice,” he said. “I ran to my room and then I saw my girl on the floor. It was so traumatising. I dropped to my knees and kept giving her chest compressions and blowing into her mouth.”

Gordon said it was history repeating itself.

He said in February 2012 Brown nearly drowned in a bath when she fell into a drunken sleep with the water running.

“It was in the Beverly Hills Hilton and the water overflowed out into the hallway,” he said. “Whitney found her, pulled her out and slept in her bed that night.”

Chillingly, Houston died the very next night.

Gordon had claimed he found the singer and tried to do CPR. However the police report contradicted his account.

“I shouldn’t have said CPR. I tried a couple of chest compressions but I knew in my heart she was gone,” he said.

Gordon says Houston took him into her home when he was 17 and Bobbi Kristina was 14. He says after Houston’s death they turned to each other and formed a romantic connection.

Gordon said he had Brown were using “more and more” drugs in the lead-up to her death and that he blames himself for not helping her. He also revealed that hse had suffered two miscarriages.

Her father, Bobby Brown, refused to allow Gordon to come to his daughter’s funeral and has made it clear that he blames her former partner.

“We believe we know who harmed Bobbi Kristina Brown and his name is Nick Gordon,” he has said.
