Bobby Brown: 'I'm Not the Reason' Whitney Houston's Gone
"I'm not the reason she's gone," he said of his ex-wife in the new interview with NBC's Matt Lauer, which will air in full on the "Today" show on Wednesday and Thursday. "I didn't get high before I met Whitney ... I smoked weed, I drank the beer, but no, I wasn't the one that got Whitney on drugs at all."
Brown said that he saw Houston just a week before her death in February, which came on the eve of the Grammy Awards.
She "had this glow about her… she looked really well," Brown said, adding that he was "hurt" by the news that cocaine was a factor in her death.
"I didn't know she was struggling with it still. But at the same time, you know-- listen, it's a hard fight. It's a hard fight to, you know, maintain sobriety that way," he said.
Houston's death at age 48 was officially ruled an accidental drowning. Cocaine, as well as marijuana, was found in her system.
Brown, who said he's "very much clean and sober from narcotics," was charged with a DUI last month in Los Angeles.
