Justin Bieber's Career Losing Steam, Sharon Osbourne Says

Sharon Osbourne predicted that Justin Bieber’s star will soon fade. “His fans are growing up -- they’re 18, 19-year-olds now. … They’re young women. And he still looks like that little boy!” she said in Sydney. She added that her gut tells her Bieber won’t stand the test of time.

Although Bieber tweeted that he wasn’t worried about Sharon’s comments, the “America’s Got Talent” judge and her gut might be onto something -- especially considering how Bieber's hoax last week to promote his new video and song seems to have backfired.

“Beauty and a Beat” failed to ignite on iTunes, with downloads putting it at only No. 50, while Bieber's album "Believe" has so far been just a modest hit.

“Tweeting that his computer and camera were stolen and then having a naked photograph that was reported to be him show up online seemed desperate,” one PR professional told me. “Next, his new official video comes out and the whole thing was a hoax! It is all so stupid. Fans never like being made a fool out of.”

Additionally, Justin has been accused of scalping his own concert tickets to inflate the value by selling them on stubhub.com.

“No artist can remain as hot as Justin was forever,” one industry insider told me. “However, creating PR stunts and silly hoaxes is not the way to prove Sharon wrong. If Justin wants to remain relevant in the long run, he should focus on putting out great music and not worry about the other stuff.”
