Brown died Sunday at the age of 22. She had been in a coma for about six months after being found face-down and unresponsive in a bathtub in January.
She died "surrounded by her family. She is finally at peace in the arms of God," Kristen Foster, a representative for the Houston family said Sunday.
Legacy Recordings, which released the posthumous album Whitney Houston Live: Her Greatest Performances, shared the family's statement online.
Singers expressed their condolences as well.
Missy Elliott sent her prayers to Brown's family.
Puff Daddy tweeted a video, showing Brown as a young girl with her family. Houston's song I Will Always Love You played in the background.
Salt-N-Pepa, an American hip hop trio, sent their blessings to her family.
Singer Monica Brown posted an Instagram picture, showing her with Bobbi Brown.
"You kept telling me life wasn't the same without Mommy," she wrote in the caption. "In all this pain and every tear I shed I find a small bit of peace knowing that [you're] with her again."
Houston, who was 48 years old when she died, was discovered in a hotel room the day before the 2012 Grammy Awards. Paramedics were unable to revive her.
"I always loved when you would say, 'Mon I need a hug,'" the caption continues. "I would lift you off the ground LOL share those hugs & that beautiful smile in Heaven."
Actress Viola Davis shared that sentiment of Brown finally reuniting with her mother in heaven.
Actress Tamera Mowry-Housley said her "heart aches" at the news.
"As a mother... I have no words."
Missy Elliott echoed that sentiment sending "extra prayers" to Brown's father, Bobby Brown, and her grandmother, Cissy Houston, who has now outlived her daughter Whitney Houston and granddaughter.
Oprah Winfrey, who interviewed Bobbi Kristina Brown shortly after her mother's death, also expressed her condolences.
