Rihanna previews new song 'Kiss It Better'

Rihanna released a preview of new song "Kiss It Better" this week.
The 26-year-old singer shared a short video with guitarist Nuno Bettencourt on Instagram. Bettencourt plays electric guitar live as another person queues a recording of the track in the background.
"Kiss It Better" hails from Rihanna's upcoming album R8. The song was written by Glass John, who produced the track with frequent Kanye West collaborator Jeff Bhasker.
Rihanna released her seventh studio album, Unapologetic, in November 2012. The record debuted at No. 1 on the Billboard 200, and includes the singles "Stay" and "Pour It Up." R8 is currently in the works, and the singer will also release a concept album based on animated feature Home.
