Brown: New disc 'can refer to an ex-girlfriend'

Chris Brown has hinted his new album 'X' is about his ex-girlfriend.

The 23-year-old singer - who recently reunited with Rihanna despite still being on probation for beating her in 2009 - has admitted a lot of his new music was inspired by a former love interest, believed to be Karrueche Tran, who he dated on and off for a year.
