Bobby Brown was on Today this morning in a taped segment with Matt Lauer, discussing Whitney Houston's death. Brown says that the last time he saw his ex-wife alive, she seemed to be "doing very well" and appeared to be sober. "I know how hard the struggle is to maintain sobriety," Brown says. "But she was doing wonderful. Everything about her was going upward." He also says that Houston was a drug user before they met, and that she introduced him to narcotics, not the other way around. "I'm not the reason she's gone," he says. "I loved that woman with everything that I had."
