It's kind of surprising that they've waited this long to do it, but Coldplay is finally getting ready to turn its Rihanna collaboration into a full-fledged single -- and to whet fans' appetites for the main event, they debuted a clip from the video during a recent live performance.

The track, titled 'Princess of China,' is the fourth single from Coldplay's quadruple-platinum 'Mylo Xyloto' album, and Rihanna's appearance was sparked by the band's desire to fiddle with genre boundaries. As vocalist Chris Martin put it to MTV, "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 claims Rihanna's vocals are his "favorite bit" on 'Mylo Xyloto,' and if this clip from the video is anything to go by, her appearance is given its visually sumptuous due. As you can see from the concert footage embedded below, it depicts her in what MTV calls "full-on goddess mode," which is fitting given that Martin recalled asking her to collaborate with the band by saying, "It took a while to pluck up the courage to ask her. We did a show in Las Vegas and I met her and said, 'Do you think there's any chance?' I was very Hugh Grant-like and spluttering about it."
