In a night filled with boisterous performances and collaborations from the likes of Kelly Clarkson, Mary J. Blige and Jennifer Hudson, rapper and Winehouse collaborator Nas emerged to introduce a 2-song tribute to his friend, who featured him on the newly released posthumous track, "Like Smoke."

"It didn't matter where she was from or what color her skin was, because Amy Winehouse was my true soul sister," Nas said in the concert special, which aired Monday (Dec. 19) on VH1. "I'm here to honor a woman who had enough soul to last a lifetime."
