Whitney\'s sister-in-law: Singer looked for love in wrong places

Whitney Houston\'s sister-in-law Patricia Houston doesn\'t appear to be holding back in a preview of her interview with Oprah Winfrey, which will air Sunday. When Winfrey inquires if Patricia thought drugs would one day cause Houston\'s death, Patricia says, \"The handwriting was kind of on the wall. I would be kidding myself to say otherwise.\" But, she continues, \"things were changing\" with Houston, and \"very much so.\" Patricia\'s fears weren\'t \"about substance abuse or anything like that relative to the latter days,\" she says. \"I think it was more of lifestyle. I was afraid for other things, lifestyle more so. I saw her chasing a dream, looking for love in all the wrong places.\" In addition to Patricia Houston, Winfrey will interview Whitney\'s brother, Gary, and the singer\'s daughter, Bobbi Kristina, in the special edition of \"Oprah\'s Next Chapter,\" which will air Sunday at 9 p.m. ET on OWN. Bobbi Kristina has reportedly explained the reason she\'s agreed to be interviewed, with TMZ citing anonymous \"friends\" who say the teen trusts Winfrey to \"be fair and respectful.\"
