Word of a new Chris Brown single may not be the most surprising thing; however, today's news about newest track 'They Don't Know' involves a surprising twist.

The song, which will be featured on Brown's next album X, will also feature several unreleased verses from Aaliyah, eleven years after her death.

The help of the late singer won't be the only guest contribution on X, as one could imagine. The album will also feature the help of Kendrick Lamar, Nicki Minaj, Pharrell, and many more.

X is set for release July 16th
