Whitney Houston's mentor has promised to launch her daughter's music career if she overcomes her personal problems.

The American singer passed away in a Los Angeles hotel room in February and since then her 18-year-old daughter Bobbi Kristina has struggled to cope.

There have been rumours the teenager is battling addiction issues and its thought her family are keen for her to get professional help to deal with her grief.

Music mogul Clive Davis guided Whitney's career and is reportedly determined that Bobbi gets the care she needs.

"Clive keeps telling Bobbi she needs to go to rehab, and that if she does, he'll help launch her music career," a source told Star magazine. "He's doing everything he can."

There has been intense speculation that Bobbi's family want her to have in-care treatment as she battles her personal problems. It's now been suggested they have even staged an intervention in a bid to help her.

"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," the insider added.

Bobbi gave an interview to Oprah Winfrey following Whitney's passing, in which she admitted she still couldn't believe her mother was dead. She also revealed plans to follow in her mother's footsteps by creating music, something Whitney supported.

"I have to carry on the legacy," Bobbi said. "We're gonna do the singing thing. Some acting, some dancing."

Whitney's mother Cissy is thought to be doing everything in her power to care for her granddaughter. The older woman hopes to keep the teenager out of the limelight until she is older and better equipped to deal with the scrutiny.
