Teen pop star Justin Bieber sported a new hairstyle, side-swept and half-shaved, while posing for pictures with fans.

The 19-year-old swapped his spiky style with shaved looks with bangs, reported Aceshowbiz.

Fans who loved the new cut commented on the new style on Twitter, saying, "Love it, love it, love it. It doesn't matter what Justin does with his hair, he always manages to look great."

Others said, "Justin Bieber's new haircut is so sexy," and, "The hair flip is back!". A fan who did not favour the new style said, "What was he thinking, his hair was lovely and now it just looks ridiculous."

Bieber, who is currently in the middle of "Believe" tour, showed up almost 3 hours late at his Dortmund concert on Friday, April 5.

According to reports, many young fans were taken home by their parents because the concert only started at 10 PM. The pop star did not apologise or offer explanations when he appeared on stage.
