James Corden revealed that he spent eight years trying to convince Rihanna to appear on his popular segment 'Carpool Karaoke' during his tenure on 'The Late Late Show.' Rihanna consistently deferred her participation, citing the release of her new album as the reason, but the album had not been released before the show ended. Despite this, Corden and Rihanna recently recorded an unexpected duet while working on the film 'Smurfs.' Rihanna was reportedly surprised to learn that Corden can sing. This marks the fulfillment of Corden's long-held dream to perform with the singer.
