The 43-year-old singer has struggled with alcohol addiction for many years. Brown told USA Today in April, Houston and Brown's reality show Being Bobby Brown gave the couple a "wakeup call" that led them to, as Brown stated, "see that our drug use had affected our relationship -- had affected the love that we felt for each other."
