Whitney Houston's family is so worried about daughter Bobbi Kristina Brown's health that they attempted to stage an intervention. Did it work?

Unfortunately, not quite. Radar Online reports that the 19-year-old hasn't stopped drinking, smoking marijuana or popping pills since her mother's tragic death in February. “Everyone is worried sick about Krissy ... Her aunt Pat got a number of her friends and family to come to Atlanta and have a serious talk with her about her sobriety,” a source said. “There were lots of tears, but Bobbi Kristina didn’t listen.”

Houston's family reportedly even tried turning to Houston's mentor, Clive Davis, for assistance. Davis allegedly offered Bobbi Kristina a career launch on the promise that she'd come clean and go to rehab.

Bobbi Kristina was hospitalized twice immediately following Houston’s death, once for stress and once for mixing alcohol with prescription sedatives. There were also reports that Bobbi Kristina got high immediately after Houston's funeral.

On a bright note, Bobbi Kristina has been cast in Tyler Perry’s new sitcom, ‘For Better or Worse,’ and seems to be happy in her relationship with her (unofficially) adopted brother. We wish her the best.
