Bobby Brown 'Sobs On Stage Over Whitney'
Whitney Houston's ex-hubby goes on with show at New Edition gig...
And the 43-year-old R&B star told the crowd in Mississippi: "I would like to say, 'I love you, Whitney'. The hardest thing for me to do is to come on this stage."
He then struggled to sing ballad Tenderoni and left the stage shortly before the song ended.
A member of his family said that he was "beyond devastated" at the news of Whitney's death.
The source said: "He wanted to tell [the family] about it before it hit the news. He didn't want any of us to hear about it on television.
"He could hardly get the words out when he called me. He was sobbing, and by the end of the call, I was sobbing too. He's beside himself right now."
Bobby and Whitney split up in 2006 and divorced in 2007.
A source had told US gossip site TMZ that Bobby had been "in and out of crying fits" after the shock news broke, but his New Edition bandmates were reported to be comforting him.
And legendary music mogul Clive Davis' annual pre-Grammy Awards dinner also went ahead at the Beverly Hilton, where Whitney's body was found yesterday.
Davis, who was Whitney's mentor and a close friend, said: "She graced this stage with her regal presence so many times. Whitney would have wanted the music to go on and her family asked us to carry on.
"I am personally devastated."
Celebs have been paying their respects to Whitney.
