Singer Whitney Houston was using crack again when she went back to rehab, RadarOnline had learned, and her use of the highly-addictive drug terrified even ex-husband Bobby Brown!
A source close to R&B star Brown said he is so worried about his ex-wife that he fears “she might not pull through.”
“Whitney is doing crack again,” the source said about the 47-year-old Houston, the singer of top 1990s hits like I’ll Always Love You. “It’s the worst it’s ever been. Whitney went on tour again, and that’s when the relapse occurred.”
Brown, 42, has also told friends that Houston, 47, has increasingly isolated herself.
“Whitney’s shutting a lot of people out of her life,” the source said. “It is a dire situation.”
Bobby and Whitney were married for 14 years and were officially divorced in 2007. Both have a history of substance abuse. Their 18-year-old daughter, Bobbi Kristina, was recently caught on camera snorting lines of cocaine.
