Brown is concerned that 18-year-old Bobbi Kristina might do “something stupid” through grief after the death of her mother.

A source said: “Bobby told family friends that he’s really worried about Bobbi Kristina.

“He knows that she is devastated about her mother dying and he doesn’t think that she is handling it well at all.

“Bobby is afraid of what is going to happen to Krissy if she doesn’t get some help – the last thing he wants is another tragedy.”

Reports say Brown wants Bobbi Kristina to go into rehab.

This comes after she disappeared for several hours after her mother’s funeral and was found getting high.

Bobbi Kristina was admitted to a rehab facility last year, it has been reported.

She was taken to hospital shortly after her mother died on February 11 for stress and anxiety.

She is said to still be in a very emotional state.

The source added: “Krissy has taken her mother’s death really hard, not surprisingly, and Bobby is terrified she’s going to do something stupid.

“He wants her in a treatment centre, getting professional help to get her through the grieving process without falling back on alcohol or drugs to mask her pain.

“Let’s face it, both her parents struggled with dependency issues and Bobby knows that addiction often runs in the genes.

So he’s terrified his daughter is going to follow in his and Whitney’s footsteps – he wants to stop that by all means possible.”

Houston and Brown’s drug use led to the eventual end of their marriage in 2007.

An insider said that Bobbi Kristina’s party lifestyle that was so similar to her mother’s, caused Houston “heartbreak” while she was alive.

The source said: “She saw her parents partying and started doing it herself.”
