SCORES of Justin Bieber fans have been fooled into shaving their heads, believing that their idol has cancer.

Internet pranksters asked the young fans to shave their heads in a show of support for Bieber and then post the photos with the hashtag 'Bald for Bieber'.

But it turned out to be a hoax and has left many of Bieber's young fans angry ... and bald.

It comes as the Canadian superstar sat down with Oprah Winfrey this week. He will appear in an upcoming episode of Oprah's Next Chapter.
