Coldplay and Rihanna will unite for the first live performance of their song "Princess of China" at the 54th Annual Grammy Awards in Los Angeles on February 12th. The song, which appears on Coldplay's latest album Mylo Xyloto, is not up for any awards, though the British quartet is nominated for Best Pop/Duo Group Performance for "Paradise" and Best Rock Song for "Every Teardrop Is A Waterfall," and Rihanna is in the running for Album of the Year and Best Pop Vocal Album for Loud.

Paul McCartney is also joining the lineup for the Grammy event, which already includes acts such as Taylor Swift, Foo Fighters, Kelly Clarkson and Jason Aldean, Bruno Mars and Nicki Minaj. Rapper-turned-actor LL Cool J will host the show, which will air on CBS, home of his hit series NCIS: Los Angeles.
