Among his many dubious claims to fame, singer Bobby Brown is the man widely credited with introducing his former wife Whitney Houston to hard drugs. 

But it seems even Whitney's death in February, which was related to her cocaine use, was not enough to halt Brown's own long history of drug and alcohol abuse.

The 43-year-old entertainer is reportedly back in rehab, less than eight weeks after his second marriage. The singer 'is once again undergoing treatment for his addiction issues,' reports TMZ.

Brown's wife of less than two months, Alicia Etheridge,told the website her husband was 'doing great'. A source told TMZ that Brown was undergoing treatment for alcohol abuse, but his wife would not confirm the particulars of his treatment. Brown was arrested for DUI on March 26, 2012, after being pulled over for allegedly using a cell phone while driving.

The hitmaker recently insisted he didn't introduce ex-wife Whitney Houston  – who died in February after suffering a heart attack partly brought on by her cocaine abuse – to drugs and felt 'hurt' by such claims as he has been sober for a long time.

He said: 'It's just unexplainable … how one could, you know, [say that I] got her addicted to drugs. I'm not the reason she's 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 didn't know she was struggling with it still. But at the same time, you know – listen, it's a hard fight.'
