Whitney Houston’s on/off boyfriend has remained quiet since the singer’s untimely death. But Ray J has finally released a statement on his late love interest: “Over the past few days, I’ve tried to process the emptiness that I am experiencing,” Ray J said. “What my heart feels cannot be expressed in words. The world lost an icon, but I lost my close friend.” He got a little more personal, adding: “Nippy, I miss you so much! You were so happy and full of love. Your smile will be in my heart forever.” On Whitney’s now infamous last night out at TruHollywood, she was actually with Ray-J and had a jealous outburst when he was talking to X-Factor star Stacy Francis. Stacy says Whitney pushed her forehead and turned her face away, before Stacy begged her to stop. After his public statement earlier today, a very somber looking Ray J linked arms with his sister Brandy, as they walked through LAX to board a plane bound for Whitney's "Home Going" ceremony in New Jersey.
