In a post-Grammys interview Justin Timberlake confirmed he'd be going on tour following the release of his third studio album, The 20/20 Experience.
But when he was pressed on the suggestion that there might be some special guests, he became evasive.
"I'm not sure how much I should say," he answered, suggesting there are special guests that the singer's keeping a secret.
Over the years JT's worked with a whole host of musical talent, some you'd expect and some a little more surprising.
Given what we already know about the album, there are a few artists who seem like obvious choices to take on tour, but JT might also opt for some slightly less obvious guests.
