Whitney Houston's daughter Bobbi Kristina dead at 22

Washington: Bobbi Kristina Brown, the only child of pop legend Whitney Houston and singer Bobby Brown, died Sunday aged 22, six months after she was found unconscious in a bathtub.

"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 family statement said.

Bobbi Kristina -- sole heir to Houston's estate -- was discovered face down and unresponsive in her bathtub in her Atlanta, Georgia home on January 31.

She was revived by emergency crews but lost significant brain function and was placed in a coma. She died at a hospice in Duluth, Georgia.

The TMZ celebrity website said that her family had decided to "take her off all meds."

Her death -- which a source told Entertainment Tonight was linked to an apparent drug overdose -- drew eerie parallels with that of her mother, who was found face down in a bathtub in a Los Angeles hotel on February 11, 2012, on the eve of the Grammy Awards.

Many Houston fans sent messages of support for the family on Twitter, saying finally Bobbi Kristina would be reunited with her mother.

"Rest In Heaven. You were loved, Bobbi Kristina Brown," actress and presenter Holly Robinson Peete said on Twitter.

Oprah Winfrey tweeted: "Peace at Last!"

Bobbi Kristina's parents separated in 2006 and divorced in 2007, with Houston awarded custody of her daughter.

They were by all accounts extremely close, with Bobbi Kristina accompanying her mother to events and awards shows.

Her parents appeared in a 2005 reality show "Being Bobby Brown" that shed some light on their personal struggles and family challenges.

After her mother's death, Bobbi Kristina -- who had hoped to follow in Houston's footsteps as a singer -- and several relatives appeared in another reality show, discussing their grieving and working on picking up the pieces.

A final coroner's report said Houston may have overdosed on drugs and alcohol before drowning, and that drug-related heart damage played a part in her death.
