US R&B star Chris Brown has revealed that he is written a series of songs which could become a collaboration with his girlfriend Rihanna.

Brown also told Billboard that he was writing songs the singer's new album – the follow-up to 2007's 'Good Girl Gone Bad'.

“I actually have a couple of songs written already that would be dope collaborations between me and her," he said.

"And I'm writing for her new album now."

Meanwhile, Brown has been named the magazine's Artist of the Year for the second time in his career.

The nineteen-year-old said he hadn't “expected” to receive the honour.
