Sam Smith might work with Rihanna

'Stay With Me' singer Sam Smith has hinted at a possible collaboration with R&B star Rihanna.

The 22-year-old Grammy-winner might appear on Rihanna's upcoming eighth studio album, which is tentatively titled 'R8', reported Aceshowbiz.

"I'm personally really excited for Rihanna's album. I know some stuff about that record that no one knows," he said.

Fans then began speculating that Smith might be singing a duet with Rihanna, writing a song for her or doing some behind-the-scenes works for her album.

'R8' is expected to finally be released later this year.
