JT is going to rock his body at Rock In Rio.
This doesn't necessarily mean Timberlake will have a new song by then, but knowing him it's likely. He's already confirmed collaborations with Timbaland, Pharrell and Max Martin on a record he's describing as a nod to his Southern roots. “[I'm not] making a country album, but I also don’t like to say that I’m making an R&B album,” JT told The Hollywood Reporter.
It's worth noting Taylor Swift has performed several arena shows without new music (unless you count her Fifty Shades Darker collaboration with Zayn), but something tells me JT isn't going to show up to the largest music festival in the world without some new audio candy for fans to indulge in.
