The superstar has taken to Instagram to share a number of cryptic posts from inside a recording studio, teasing new tunes.
Bieber, 23, is photographed with headphones on, in front of a microphone with a sheet of what looks like music lyrics blurred out.
Another black-and-white snap shows the 'What Do You Mean?' singer playing a keyboard, his arm tattoos on full display.
Bieber's manager re-posted one of the photos with the caption: "The world has no idea!! @justinbieber 🌎".
The singer released his last album Purpose in 2015, and last month was in Australia on his Purpose World Tour.
