Bobby Brown is back in rehab

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.'

Brown's wife of less than two months, Alicia Etheridge, told TMZ 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.
