"What my heart feels cannot be expressed in words," he added. "The world lost an icon, but I lost my close friend."

Then calling Houston by her nickname, Ray J said, "Nippy, I miss you so much!"

Houston died in a hotel suite in Beverly Hills, Calif., last Saturday. A source said Ray J rushed over to the Beverly Hilton hotel as soon as he heard the news. He "spent the night comforting [Houston's daughter] Bobbi Kristina," an insider told Us Weekly. "He's absolutely devastated."
