Justin Bieber has hinted that he could soon put out an acoustic album.

The pop superstar posted a picture of a selection of guitars on Instagram yesterday (9 August), and captioned the photo: “Acoustic album?”

To give fans a little glimpse of his guitar-playing skills, he played a few notes of Dust In The Wind - sharing the video with followers.

And the Aussie popstar suggested that his collaboration with JB could be “a little more than a song”.

Biebs has also been busy working solo in the studio, and teased no less than eleven new songs on Instagram last month.
