Coldplay have posted online an acoustic version of their Rihanna collaboration 'Princess of China'.

The track originally came off the band's 2011 album 'Mylo Xyloto', but an acoustic version of the song has now been made available.

The song, which was uploaded online today (June 25), is also available to buy on iTunes.

Coldplay meanwhile recently went on record to praise Rihanna and state that she was always first choice to sing the track.

As previously reported, Coldplay called the singer an "incredible artist" and said that they all "love her".
