X is the upcoming sixth studio album by American recording artist Chris Brown, scheduled for release in June or July 2013. On the album Brown has worked with artists and producers such as Pharrell, Kendrick Lamar, Rihanna, Nicki Minaj, Wiz Khalifa, Timbaland, Diplo, Danja and DJ RoccStar among others. Brown stated that the album's title ‘X' defines everything he's been through in his life, stating: "It's the Roman numeral for 10. 5/5/89 is my birthday: 5 plus 5 is 10, and this is my tenth years since I got into music. 'X' is the 24th letter in the alphabet, and I will turn 24 when this album comes out. 'X' is also a metaphor, as in 'ex-girlfriend': it implies you're progressing and moving on in life, not holding on to the past and your old ways".
