On her Twitter page, the singer (who wore a black Jenny Packham gown to the service) says she was just too overcome with emotion. As Carey sang the song with frequent collaborator Trey Lorenz, photos of Jackson flashed on a huge screen above them.
"Trying to sing today was basically impossible for me," writes Carey. "I could barely keep myself from crying. I'm sorry that I wasn't able to pull it together and really do it right, but I was literally choked up when I saw him there in front of me."
"One thing I know is, we will never really have to say goodbye to MJ. His legacy lives on through his music and the millions of people [h]e inspired with his timeless music. He will be forever in our hearts," she adds.
