Jay-Z has revealed that he hopes to collaborate with Coldplay's Chris Martin on his new album.

The pair previously worked together on Jay-Z's 2006 track 'Beach Chair' and on Coldplay's 'Lost'.

"If he'll allow me... any time you can collaborate with that sort of genius, you jump at the chance, I don't care who you are," Jay-Z told BBC Newsbeat.

He added: "He's a brother from another mother. I see him more than my own brother. Actually, I do!"

Jay-Z and Chris Martin are set to perform together on New Year's Eve at the Cosmopolitan casino in Las Vegas.

Meanwhile, Jay-Z has signed X Factor contestant Cher Lloyd to his Roc Nation label, it has been reported.
