The 20-year-old didn't offer any information on the clips — except for one captioned Cold Waters — or confirm whether a album is in the works.
But he did offer his fans a tweet:
Social media stunts are becoming more common among artists looking for fresh ways to grab attention and sell albums.
Singer Beyoncé Knowles surprised fans last December when she released a full-length, self-titled album on iTunes with no warning.
Justin Bieber also has a reputation for using social media to generate buzz.
In 2013, he teased his album Journals with a 10-week digital download campaign, releasing a new song every Monday night for three months.
This is the first time in a while, however, that the pop star is making headlines for his music instead of his antics.
Bieber is currently serving two years probation for pelting his Los Angeles neighbour's home with eggs.
He was also ordered to pay $80,900 U.S. in restitution, serve five days community service and complete an anger management program in what the district attorney called a negotiated settlement.
