The two acts are sounding "beautiful" according to a close friend of the band.
Rihanna and Coldplay's Chris Martin have been busy rehearsing for the two acts' duet at this year's Grammy Awards on Sunday (12th February).
The pair will perform 'Princess Of China' at the ceremony and according to the band's "unofficial fifth member" Phil Harvey – it should be one of the stand out performances of the night.
"Chris and rihanna just rehearsed princess. Absolutely beautiful. PH," he tweeted on the band's Twitter account earlier today (10th February).
Both acts are also due to attend this month's BRIT Awards and could team up once again to perform the track.
It is also rumoured Chris Martin may join former Oasis man Noel Gallagher on stage at the event.
Meanwhile, Cee Lo Green recently confessed that he believes RiRi's "sexually charged" performances inspire her lesbian fans.
