What Chris Brown Did: Recorded a song called "Don't Think They Know" featuring Aaliyah vocals
When He Did It: June 2013
Why It Was So Controversial: Chris Brown's nemesis Drake has shown a real interest in Aaliyah in recent years, even going as far as getting her image tattooed on his back. This was controversial because of that, but also because it caused Timbaland to go on a huge rant about how much he hates artists who didn't know Aaliyah using her vocals on tracks. Timbo eventually came around to Chris Brown's song and apologized to him. But this song was still the center of a whole lot of controversy over the summer.
