husband Bobby Brown struck back at claims he was responsible for getting the pop star hooked on drugs or that he somehow played a role in her cocaine-fueled death in February. “I'm not the one that got Whitney on drugs, at all,” Brown said in an interview to be aired this week on the “Today” show on U.S. television network NBC. “I'm not the reason she's gone,” he added. Houston, 48, was found dead in a Beverly Hills hotel bathtub on Feb.11 from what authorities called accidental drowning brought on by cocaine use and heart disease. White powder and drug paraphernalia were found in the bathroom where she died. The singer had spoken publicly about a long battle with cocaine, marijuana and crack, particularly during her tempestuous 15-year marriage to Brown. They divorced in 2007, but some fans and members of Houston's family have blamed Brown for her untimely death. In his first TV interview since the singer died, Brown, 43, told “Today” show host Matt Lauer that he had been off drugs for seven years and was hurt to hear that Houston had been using cocaine.
