Bieber teases new music online
Justin Bieber has treated fans to snippets from 11 new tracks posted online.
The 20-year-old singer has uploaded the videos to Instagram which show blurred and dingy shots of a recording studio, while clips from previously unheard tracks can be heard playing.
Justin tweeted: "Great night in the studio" and later added: "I love music".
He captioned the first video Cold Waters, which appears to be the title of the accompanying song, with other lines including "Try to bring me down... cause they got nothing nice to say."
The lyrics come after a rocky year, with several run-ins with the law, for Justin, who has been heavily criticised on social media.
Another track simply has an emoji of a princess crown and appears to be a love song, while all the others are untitled.
All the music has a strong R 'n' B sound with a focus on relationships, and one track seems to be about a break-up, with a line including: " I'm moving on," which could be a reference to his longtime on-off girlfriend Selena Gomez.
Justin was recently pictured recording new music with Chris Brown, although the pair have not yet spoken about the collaboration.
It is not known if the new tracks are to form an album. The Canadian singer released his third studio album, Believe in 2012, and a compilation album, Journals in 2013.
