Rihanna, Coldplay to sing Grammy Award duet in February

Rihanna appears on Coldplay's most recent album Mylo Xyloto

Rihanna has confirmed that she will duet with Coldplay at next month's Grammy Awards.

The singer says she will take to the stage with the British rockers to perform their recent collaboration, Princess Of China.

Tweeting about the duet, Rihanna described it as "bonkers" and "great news".

LL Cool J will host the ceremony which will also see live performances from Lady Gaga, Bruno Mars and Foo Fighters.

Coldplay front man Chris Martin has spoken of his admiration for the singer in the past.

In October 2011, speaking to Radio 1, he said he didn't think it was an usual collaboration.

He said: "Don't you think that music now shouldn't fall into a particular box? I don't think anyone thinks like that any more."

Kanye West has the most nominations for this year's Grammy Awards with seven, including song of the year for All Of The Lights.

Adele is nominated for six Grammys after her hugely successful year in America, where she scored both the best-selling single and album of 2011.

It is not yet known whether she will perform at the ceremony following surgery on her vocal cords in November.

The Grammy Awards are set to take place on 12 February in Los Angeles.
