Bobby Brown surprised by Whitney`s drug intake

London: Whitney Houstoun`s ex-husband Bobby Brown says he was shocked to discover that his former wife was taking drugs before she died.

Houston, 48, died in Beverly Hills in February from accidental drowning caused by cocaine use, reported Contactmusic. "It is just unexplainable... How one could, you know, (say that I) got her addicted to drugs. I am not the reason she is gone. "I was hurt... Because, you know, me being off of narcotics for the last seven years, I felt that she was, you know, I did not know she was struggling with it still. But at the same time, you know, listen, it is a hard fight. It is a hard fight to, you know, maintain sobriety that way," Brown said. Houston had apparently wanted to reunite with her former husband of 14 years and the pair had decided on an intimate ceremony with their daughter Bobbi Kristina as the only witness. PTI
