Chris Brown says he'll be using never-before-heard vocals from the late singer Aaliyah on his new single "They Don't Know."

Looks like Chris Brown is paying tribute to Aaliyah with a new track that will feature the late R&B star.  He announced the news at the BET nominations press conference on Tuesday, saying the song titled "They Don't Know," will be the next single off his forthcoming album, X. It will features rare, unreleased vocals from Aaliyah, who died tragically in a plane crash in August, 2001.  Wait, didn't Drake just do the same thing?  Your thoughts?
