Rihanna and Chris Brown Rihanna and Chris Brown

It's been just over three years since singer Chris Brown attacked then-girlfriend Rihanna at a pre-Grammy Awards party in 2009, but it seems the former couple has reconciled.

The duo collaborated on two new songs that were released earlier this week. Rihanna is featured on Brown's "Turn Up The Music," and similarly, Brown sings on a remixed version of Rihanna's "Birthday Cake."
