Mariah Carey, who recently told “Good Morning America” that the death of Whitney Houston was “very heavy emotionally” for her, has now posted a video tribute to Houston on YouTube.

The two-minute clip titled “Whitney Houston & Mariah Carey – Favorite Moments” — features footage and pictures of Carey and Houston at several joint appearances over the years set to the backdrop of their 1998 duet, “When You Believe.”

“I don’t think people could ever understand our relationship,” Carey tells GMA. “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.”
