Sales of Bieber's album Believe Acoustic — featuring new tracks as well as stripped-down versions of previous uptempo hits — sent it to the top of the Billboard 200 album chart during its first week of release, according to figures released by Nielsen SoundScan on Wednesday. It sold 211,000 copies over the past week.
"We did it! #HISTORY," the singer declared to his more than 34 million followers on Twitter.
"Let's keep it going...Hope you are enjoying the albums and the music. That is what it is all about."
The album also soared to the top of the iTunes download charts in more than 60 countries.
Bieber had previously been tied for the album record with former Disney child star Miley Cyrus, who also had four No. 1 albums before the age of 19.
His earlier chart-toppers include 2012's Believe, 2011's Under the Mistletoe and 2010's My World 2.0. He burst onto the scene in 2009 with My World.
The Canadian singer, who celebrates his 19th birthday on March 1, has also now joined a rarified company of artists who have released four No. 1 albums in consecutive years. Others include The Beatles and rapper Jay-Z.
Bieber will host and perform as the musical guest on longrunning sketch comedy showSaturday Night Live this weekend, airing the night before the Grammy Awards. The singer failed to pick up a Grammy nomination despite his bestselling album and having had a sold-out tour.
Fellow Canadians Tegan and Sara also landed in the top five of the Billboard chart this week, landing in third place for their new album Heartthrob.
