Hundreds of people have gathered in suburban Atlanta to pray for the late Whitney Houston's daughter, who is fighting for her life in a hospital after being found face-down in a bathtub.

The Shining a Light for Healing for Bobbi Kristina Brown vigil was held at the Riverdale Town Center Amphitheatre on Monday night.

Bobbi Kristina is the only child between Bobby Brown and Houston. Her relatives have said she is "fighting for her life" at an Atlanta hospital.

Police, citing an ongoing investigation, have not disclosed many details on the circumstances in which Brown was found.

It was nearly three years ago when Houston was found dead in a bathtub.

Several vigil speakers touched on the struggles and scrutiny Brown's family has faced in recent years, comparing them to their own trials and tribulations.

"They bleed and hurt like us," Wynn-Dixon told the crowd before singing the gospel song There's A Leak In This Old Building.
