Rihanna and Coldplay are performing together at the Grammy Awards.

The Barbados-born singer has confirmed she will be taking to the stage with the British rockers at the ceremony, which is being held on February 12 2012.

Rihanna announced the news on Twitter and seemed thrilled about the plan.

'My friends @ColdPlay and I will be sharing the stage for a performance at this years Annual Grammy Awards! #BONKERS (sic),' she wrote.

It's thought Rihanna and Coldplay will perform their duet Princess of China, which is featured on the band's record Mylo Xyloto.

Lead singer of the group Chris Martin has previously spoken of his excitement about working with Rihanna.

'In like a dream scenario, we had a song that I'd secretly kind of written to see if Rihanna would want to sing it. And then the rest of the band wanted to keep it, so we came up with the idea of asking her to sing it with us, and, to our great surprise, she said OK,' he explained.

'Well, her bit on our record is my favourite bit. When the song came out, it sort of asked for her to be on it.'
