Cape Town - Rihanna's new single has hit the web, reports Digital Spy.
Diamonds, written by Australian singer-songwriter Sia and produced by Benny Blanco, is the first single off Rihanna's forthcoming, as yet untitled album.
It will be the pop diva's seventh studio offering which is reportedly due for release in late November 2012.
The singer spoke about her new single during an interview at the iHeartRadio Festival.
She said: "The lyrics are very hopeful and positive, but it's about love and... a little different to what people would expect, I think."
Late on Wednesday Rihanna's Facebook page announced that the track is now available for download on iTunes.
Rihanna has served up many chart-topping singles from her previous albums, with her track We Found Love being touted as one of the most successful singles of all time.
Promotion for her upcoming album kicked off with the website rihanna7.com, and simply features a new logo with the hastag #R7.
