Last month, in a traumatic couple of days, Bobbi Kristina lost her mother, Whitney Houston, and was hospitalized for stress and anxiety. She's been a tabloid fixture ever since, and some say she's spiraling out of control and heading toward rehab. Now, the world will get the story straight from the source, as the 18-year-old has agreed to chat with Oprah Winfrey.

As TMZ reports, the only child of Whitney and bad-boy singer Bobby Brown will appear next Sunday on 'Oprah's Next Chapter.' The late singer's sister-in-law and manager, Patricia Houston, will also chat with the TV icon, as will her brother Gary.

In related news, Brandy, Whitney's costar in the 1997 TV movie 'Cinderalla,' opted against including any of Houston's songs in her performance last night in Los Angeles, TMZ reports.

It was Brandy's first show since Whitney's death on Feb. 11, and rather than cover one of the late R&B great's classics -- something she said would have made her "an emotional wreck," according to the gossip site -- she dedicated the song 'Right Here (Departed).'
