Justin Bieber's fame continues to soar up the charts. With a massive fan base, a overly-supportive girlfriend and family, it's no wonder why Justin Bieber is still at the top of the Hollywood music scene. However, for one big shot in the business, namely Sharon Osbourne, Justin Bieber's famous days are numbered.

"Beliebers" clearly believe that Justin will continue to make music even by the time the Canadian crooner turns 23. Yet, for Sharon Osbourne, that won't likely be the case. In an interview with the National Radio in Sydney, the former "X-Factor" judge openly dissed Bieber along with his hair.

"For me, Justin is.. I've met him, I've worked with him, I did a TV commercial with him. He's a really great little guy. But that's his problem," says Osbourne

"He's a little guy. His fans are growing up, they're eighteen, nineteen year olds now. And that means the little girls of titties and lips (sic), you know they're young women. And he still looks like that little boy!" added Sharon.

Apart from calling the 18-year old teenage heartthrob a "little guy", Sharon had also commented on Bieber's hairstyle.

"He needs some hair, or something. I just don't think, from my gut, maybe my guts wrong 'cos it's not a hundred per cent, but I don't think he's going to stand the test of time. But you know what, I don't feel sorry for him, because he's made oodles and he's a fabulously nice person and he'll go on to do something else," said Sharon.

Well, judging from how "Take That" and "Backstreet Boys" have gone from teenage icons to succesfull adults in the business, Justin Bieber won't likely fail at success. Justin does have his mother, Pattie Mallette, to turn to for advice and an equally talented girlfriend, Selena Gomez for inspiration.

At the end of the day, week or year, "Beliebers" are best to decide if Justin's fame will continue to soar or not. The only thing Sharon Osbourne should worry about is Justin Bieber fans' back lash for calling their idol a "little guy" plus commenting on Bieber's hair.
