Bobbi Kristina Brown's aunt, Pat Houston, says the late star was headed to rehab before she was found unresponsive in a bathtub at her home in January this year. Brown, the only child of Whitney Houston and Bobby Brown, died six months later on July 26, as HNGN previously reported.

"As Whitney Houston's manager, confidante and sister-in-law, Pat was like a second mother to Bobbi Kristina, and says she was planning an intervention" before the then 21-year-old was found unconscious, according to Entertainment Tonight.

"When we really found out that Krissy was in trouble, we were really making plans to do something about it," said Houston, who added that she also wanted to send Bobbi Kristina to a rehab facility in Georgia, "but it came too late."

A lawsuit by her Atlanta conservator has alleged that Brown's boyfriend, Nick Gordon, gave her something toxic that led to her death, but it has not been confirmed by the medical examiner and Gordon has not been charged by local prosecutors, according to USA Today.

Houston always doubted Gordon and even filed a restraining order against him last year after she said he threatened to kill her, but it didn't have the intended effect, because Brown "didn't understand it," said Houston.

"Where the world saw that she was angry and mad at me, she was texting me all along," she said. "I really tried to show her [that] I'm going to do this to let you know that you don't have to be afraid of anything. I got you.'"

"External attraction can really cause problems," Houston added, referring to the romantic relationship between Brown and Gordon.

Coping with the loss of Brown has been extremely difficult, because the family was still trying to come to terms with her mother's death in 2012. In the interview, Houston recounted the time she and the family revisited the hotel room where Whitney Houston died.

"When we went into the room, it was just so peaceful and calm and the room was lit - it was like it was candle lit. It was just very, very calming," Houston said. "I went into the bathroom and I placed the flowers at the tub and I just sat there and just was thinking, 'What happened? How did we get here?'"

Houston opened up about the things she would've told her niece if she had the chance to speak to her again. "You have to love yourself," she said. "You have to call on people and not allow someone to divide you and then conquer you."
