Rihanna To Perform With Coldplay At Grammys

Rihanna and : Coldplay will perform live together for the first time on February 12 when they take the stage at the 54th annual Grammy Awards for the televised debut of their Mylo Xyloto collaboration, "Princess of China."

Rihanna, nominated for four Grammys this year, broke the news on twitter, writing, "My friends @ColdPlay and I will be sharing the stage for a performance at this years Annual Grammy Awards!" A short time later she added, "WE reached 2BILLION views on @youtube !!! THANK U!!! I'm in a great mood, and I got some GREAT NEWS!!! PRINCESS OF CHINA #GRAMMYS2012."

The show, which will be hosted by rapper LL Cool J, will also feature a performance by rock icon Paul McCartney, who will join a lineup that already includes
 Grammy nominees Foo Fighters, Kelly Clarkson, Bruno Marks, Nicki Minaj, Taylor Swift and Jason Aldean.

At the time Xyloto was released
, Coldplay singer Chris Martin explained that the decision to invite another voice into the studio was made because of the unusual story arc of the band's Grammy-nominated album.

"Her bit on our record is my favorite bit. ... When the song came out, it sort of asked for her to be on it. And I think at this point, we have nothing to lose, and so we've been trying some new things and trying to break down the perceived boundaries between different types of music," Martin told.

"Our new record is sort of a story; it's not quite a musical, but it's dangerously close. There's a bit of a love-story thread, so we really needed someone to sing even higher than me," Martin said. "[It's] hard, but very possible. You need to be a female really. For all [drummer] Will [Champion]'s good intentions, he [can't do it] ...

"... So, 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," Martin continued. "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."

More Grammy performers and presenters will be announced in the coming weeks.
