WOODBURY - Whitney Houston's ex-husband Bobby Brown is back in Los Angeles this morning with their daughter.

Brown found out about Houston's death just before his concert in Mississippi Saturday night.

Brown was reportedly crying and had to walk off the stage.

Brown arrived in Los Angeles yesterday to be with their 18-year-old daughter Bobbi Kristina.

Bobbi Kristina was rushed by ambulance to the hospital yesterday morning to be treated for anxiety and stress.

The teen has been taken to the hospital twice since her mother's death.

Family members reportedly fear she may try to take her own life.
