"Well, I felt as though I had to. Again, just the same as I hear my mother's voice in my head, I can hear my brother's voice in my head," said Hudson. "Everybody, is like, 'Is she ever gonna sing again?' And what was I gonna say to that?"
J-Hud also confesses that she felt a strong obligation to perform again so that her family would be proud of her.
"I could hear him, like, 'Jennifer--' he would always say, 'Knock it off, Jenny,' if I was cryin' about somethin' or if I was upset, discouraged, mad, 'Jenny, knock it off.' That's what I hear in my head. I can either just sit here and mope around, or do what I know that would make them proud.' And that's what I did," said Hudson.
