Los Angeles, July 27 (IANS): Late singer Whitney Houston's daughter Bobbi Kristina Brown, who was in a medically-induced coma for almost six months, died on Sunday at the age of 22, a family representative said.

"Bobbi Kristina Brown passed away Sunday, July, 26 2015, surrounded by her family. She is finally at peace in the arms of god. We want to again thank everyone for their tremendous amount of love and support during these last few months," a statement from the representative read, CNN reported.

Bobbi Kristina was treated in a hospital and then a hospice facility after she was found unresponsive and not breathing in the bathtub at her Roswell home on January 31 -- nearly three years to the day after her mother accidentally drowned in a bathtub in Beverly Hills, a victim of the vices she had fought for much of her career.

She was initially taken to North Fulton Hospital and placed in a medically induced coma, and was later transferred to Emory University Hospital in Atlanta, where she was on life support in the neuro intensive care unit.

Born to Houston and singer Bobby Brown a year after they married in 1992, Bobbi Kristina was a singer as well as reality TV personality. She had grown closer to her mother after Houston's divorce from Bobby in 2007.

Her mother's death shook Bobbi Kristina, who had opened up to Oprah Winfrey during an interview in March 2012 about how she was coping with the loss.

"No one knows what an amazing spirit she was. She wasn't only a mother, she was a best friend," she had told Winfrey.

Bobbi Kristina, who in 2012 made her acting debut on Tyler Perry's show "For Better or Worse", was joined in her grief by Nick Gordon, who was taken in by Houston when he was 12-years-old and who was raised alongside her.

Gordon and Bobbi Kristina became romantically involved after the singers's death, and tensions between the Gordon and Houston families over the relationship were part of the storyline on short-lived reality show "The Houstons: On Our Own".

Bobbi Kristina and Gordon announced their engagement in 2013 and she took to her social networking website Facebook page to clear up the misconception that he was her adopted brother.

It was Gordon and a male friend who discovered Bobbi Kristina unconscious in her house.

While Bobbi Kristina called Gordon her husband, there is no court record of a marriage between the two and family members say the couple was never legally wed.

After she was found in the bathtub, authorities launched a criminal investigation.

A family friend said police questioned Gordon about the bruising on Bobbi Kristina's chest and said he told them it was a result of his giving her CPR.

In June, a civil lawsuit was filed against Gordon in the Superior Court of Fulton County, Georgia, alleging that Gordon's behaviour "caused, among other things, substantial bodily harm to Brown".

It also alleged that since Bobbi Kristina's hospitalisation in January, Gordon accessed her bank accounts and stole more than $11,000.
