(Cover) - EN Showbiz - Whitney Houston has reportedly decided she needs more addiction help after finishing an out-patient rehab programme this week.

The 47-year-old singer has battled substance abuse in the past and last month it was revealed she had decided to seek help for her personal problems. Her representative confirmed she was receiving drug and alcohol treatment, but further details weren't revealed.

According to website TMZ Whitney finished that round of rehab earlier this week, but has decided it wasn't enough. "Sources close to Whitney wouldn't elaborate on what the additional treatment entails - but we're told the singer has hired a round-the-clock life coach to help keep her on track," the site reports.

It was Whitney's decision to get out-patient care as she is dedicated to getting better. It's thought she was allowed out in public while completing the programme as long as she was with a monitor.

"She really wants it this time," a source said.

Whitney previously sought professional help in 2004 and 2005, and last year she blasted claims a drug relapse had caused her to postpone the first dates of her European tour. She spent time in hospital due to an upper respiratory infection, but there was instant speculation she'd actually being abusing substances again.

"Reports that I was ill due to drugs are ridiculous," she said. "At this point, I just don't respond. I don't even read it. My health is terrific but this is a time when I get a lot of allergies." (C) Cover Media
