Whitney Houston's sister in law, and some say, her closest confidante, say it wasn't drugs or foul play that cause the singer's demise. It was her love life!! Whitney's sister-in-law, Patricia Houston, sits down with Oprah Winfrey in an interview that airs this weekend and she blames Whitney's love life for her death. Patricia says before Whitney's untimely death, "things were changing, things were really changing [for her.]" She explains: "It wasn't about substance abuse relative to the latter days or anything like that. I was afraid for other things...lifestyle [things]...I saw her chasing a dream--looking for love in all the wrong places." She won't mention names, but she could be referring to Ray-J who was dating Whitney on and off before her death. Patricia admits she even had premonitions of Whitney's early death, saying "The handwriting was kind of on the wall. I would be kidding myself to say otherwise."
