Bobby Brown feels like Bobbi Kristina’s death is his fault, says a report. His daughter died at 22 after six months of hospitalization. Now, beset by guilt, the R&B singer wishes he would have become her legal guardian and forced her into rehab, the U.K.’s Daily Mail wrote in an exclusive report Wednesday.

One of the things Bobby wishes he would have done is keep his daughter away from her boyfriend, Nick Gordon, who is considered a person of interest in her death, which has been ruled a homicide. “He told me he should have insisted Krissy get help for her drug addiction and he should have forced Nick Gordon to move out of her townhouse and leave her alone -- legally, if necessary,” an insider told the Daily Mail.

A preliminary autopsy did not show any serious injuries, but it will be weeks before a toxicology report reveals whether there were drugs in her system. Though many people suspect Bobbi Kristina was abusing drugs, none were found by authorities when she was discovered facedown and unconscious in a bathtub in her Roswell, Georgia, home on Jan. 31.

But Bobby is finding it hard to cope with his daughter’s death. “Bobby has so much guilt that it is eating him up every day,” the source said. “Bobby says he was her father no matter what age she was and he should have fought her or anyone else who stopped her from saving her from herself.”

The National Enquirer may have added to the family's pain Wednesday when it published a supposed photo of Bobbi Kristina on her deathbed. The image has not been verified, but the publication claims to have “more chilling images inside.” They also reprinted the controversial photo of her late mother, Whitney Houston, in her casket.
