UPDATE: Tyler Perry has denied that Bobbi Kristina walked off the set, per TMZ. The original version of this article appears below.
Still reeling from the death of her mother, Whitney Houston, Bobbi Kristina Brown walked off the set of her new TV show, the TBS comedy "Tyler Perry's For Better or Worse," reports RadarOnline.com.
Brown, 19, had only shot a few episodes of the show -- the next season airs in July.
“She thought she was ready for this, but she wasn’t,” an insider told RadarOnline.com, adding that she collapsed into tears.
So far, Brown is still doing her Lifetime reality show, "The Houston Family Chronicles."
It's been a difficult time for Brown, who was rushed to the hospital and treated for anxiety soon after her mother's death. Amid reports of drug abuse, she also has reportedly considered changing her last name to distance herself from her dad, Bobby Brown, and may not attend his upcoming wedding to Alicia Etheridge.
The elder Brown addressed some of those rumors on MTV recently, telling the network: "She can't change her last name, her name is her name. She'll forever be known as Bobbi Kristina Brown. There's no changing that, there's no taking that back."
