The singer and sometime reality television star was one of the people who spent time with Houston in her last days.
He told reporters at a charity event on Friday in Los Angeles: "I really miss my friend, you know. I really do. I'm still hurting."
"I'm able to look at life in a whole different way," Ray J said. He looked down at a smartphone and said, "I always look at my phone because I've got a picture of somebody that I really love and it helps me through the day."
Ray J, who was joined by his parents Sonja and Willie Norwood, did not take questions from reporters.
