Rihanna and Florence Welch have collaborated on a track which is thought to be being saved for the Barbadian singer's forthcoming album, tentatively titled 'R8'.
Titled 'A Night', it lists Florence and award-winning producer Paul Epworth as writers on the song, leading to speculation it could sample a track from Florence's 2011 album 'Ceremonials' titled 'Only If For A Night'.
Details about Rihanna's new album have been sketchy, but Sia and Kiesza have previously confirmed they're involved, with Sam Smith even hinting he's recorded with the star for the LP.
He teased recently: "I'm personally very excited for Rihanna's album. I know some stuff about that record that no one knows."
Her first record release since 2012, it's also expected to feature leaked track 'World Peace'.
However the chart-topper's done her best to tone down speculation around the album, saying she and she only is the only official source of information.
On Twitter she wrote in November: "ANY news about #R8 will be delivered directly from me!!!!"
