The singer will premiere her new cut 'Diamonds' on radio later today (September 26), with the track to be available to download in the US shortly after.
The track was penned by Sia, whose previous hits and writing credits include David Guetta's 'Titanium' and Flo Rida's 'Wild Ones'.
The lyrics in the first verse for Rihanna's 'Diamonds' include: "Find light in the beautiful sea/ I choose to be happy/ You and I, you and I/ We're like diamonds in the sky."
The chorus centres around the hook: "So shine bright, tonight you and I/ We're like beautiful diamonds in the sky/ Eye to eye, so alive/ We're like beautiful diamonds in the sky."
'Diamonds' was produced by Benny Blanco and will serve as the lead single from Rihanna's upcoming seventh studio album, due out in November.
