Bobbi Kristina Brown needs her father more than ever.

After a brief, stress-releated check-in, the late Whitney Houston's 18-year-old's daughter has been been released from Cedars-Sinai Hospital in Los Angeles -- and her father, Bobby Brown, is en route to Los Angeles to be by her side, E! News confirms.

Bobby, 43, canceled a Sunday concert gig with New Edition in Nashville, Tennessee, and boarded a flight back to Los Angeles.

The "My Prerogative" singer lost it onstage Saturday night at a show in Southaven, Miss., hours after ex-wife Houston was pronounced dead in her hotel room in Beverly Hills.

"Just say a prayer for my daughter, say a prayer for her mother, and if you find the time please say a prayer for me because I am going to need it," Brown told the crowd.

His daughter is having a "total breakdown," one source told Us. "She is freaking out, uncontrollably sobbing. We thought she was trying to kill herself. Everybody is worried."
