According to a source close to troubled diva Whitney Houston, it was her mom, gospel singer Cissy Houston, who petitioned a Georgia court to order her famous daughter to seek help in a rehab facility in March, PEOPLE has learned.
Whitney eventually entered the Crossroads treatment center (founded by musician Eric Clapton) in Antigua, West Indies, leaving in late April after almost a month. She rejoined the family in an undisclosed Caribbean spot, an insider tells PEOPLE.
Her rep confirms that Houston is "entering the second phase of her treatment." Cissy's rep had no comment.
Whitney's March rehab visit marked the second time the 41-year-old singer has sought treatment in just over a year. In March 2004, she entered rehab for substance abuse. She checked out just five days later to begin private care.
"I'm finally completely me again," Houston told PEOPLE after last year's treatment. "I feel much stronger than ever before."
Meanwhile, plans for a reality show featuring Houston's husband, Bobby Brown, moved forward with the announcement that eight 30-minute episodes of Being Bobby Brown will air on Bravo starting June 30. The cable network promises that "the series will demystify Brown's relationships with Houston" and their daughter Bobbi Kristina, among other things.
