*Rihanna and Coldplay are set to bring their collaboration “Princess Of China” to the stage of the 54th Grammy Awards.

RiRi, who is nominated for four Grammys including album of the year for “Loud,” tweeted the news to her followers Wednesday night, calling it “BONKERS.”

Coldplay, meanwhile, is up for three awards.

The two camps confirmed in September that they’d written a track together, with the resultant “Princess Of China” becoming one of the most pop-orientated numbers on Coldplay’s fifth studio album “Mylo Xyloto.” [Listen to the track below.]

As previously reported, LL Cool J will host the CBS show, to be broadcast on Feb. 12 from the Staples Center in Los Angeles.

Paul McCartney was announced Thursday by The Recording Academy as another performer added to the ceremony. The ex-Beatle is being honored during Grammy week as the MusiCares person of the year. His new album, “Kisses on the Bottom,” will be released Feb. 7.

Other Grammy performers include the Foo Fighters, Taylor Swift, Bruno Mars and Jason Aldean.
