Apparently the crack is back... and not wack! Recent reports indicate the ex-husband to R&B Superstar Whitney Houston, Bobby Brown is more worried than ever that her demons have resurfaced. He is scared for her life. An insider to the singer even said that Bobby thinks that Whitney's drug problem is so bad now that she may not be able to pull thru.

An insider says that Whitney went on tour again, and that's when the relapse occured. The insider also says that "I've never seen it this bad."

“Whitney is doing crack again,” a source close to the 1990s hits like “I Will Always Love You” said. “It’s the worst it’s ever been. Whitney went on tour again, and that’s when the relapse occurred.”

If Bobby Brown is that worried, you KNOW it nust be bad...

We wish Whitney the best in her situation!
