Mariah Carey described herself as "almost incapable" still of talking about Houston's death, Carey began there, reflecting on the "home-going" service she attended Saturday for Whitney Houston.
"It was great," she said of the nearly four-hour funeral. "Such a class act, the way she went out and the way her family dealt with it.
"I don't think people could ever understand our relationship," Mariah said of Houston, with whom she recorded the hit "When You Believe" in 1998.
"There was always this supposed rivalry in the beginning and then we did the duet and became friends. I saw her towards the end. I loved her. It's very heavy emotionally."
