Shoe have to be kidding! Justin Bieber fever has yet to kick off as he auctions his trainers for charity

The mere mention of his name is renowned for sending young girls giddy with delight.

So the news teen sensation Justin Bieber is auctioning a pair of his worn Supra trainers for charity should have been enough to kick off a bidding frenzy.

Bieber Fever has failed to take hold however, as just four bids have been made despite the lot being open since July 19.

Charity auction website charitybuzz.com will be hoping there will be a last minute stampede to land the unique item, as the proceeds are being used to benefit the Ovarian Cancer Research Fund.

Bidding for the shoes closes next Wednesday, so there is still plenty of time for fans to get in line.

One crumb of comfort for auction organisers is the fact $900 has already been bid for the sweaty sneakers, which is nothing to be sniffed at.

However the revelation will add more credence to claims the singer's popularity is finally declining after his near omnipresence over the last few years.

Bieber, who is dating teen favourite Selena Gomez, burst onto the music scene two years ago as a cutesy, clean-cut pop sensation.

But it would seem Justin Bieber is becoming quite the rebel these days.

Earlier this week the 17-year-old star was spotted wearing a T-shirt which literally turned the air blue with an unmissable, unsavoury song lyric printed in huge white writing.

The line is taken from the original version of the Cee Lo Green track, Forget You, and read: 'F*** you and f*** her too.'

With some swagger in his step, the cocksure singer strode out of the Armani Exchange shop in Sunset Plaza, Los Angeles, where he had just purchased some new clothes, perhaps including new shoes.

However the lazy vocalist let his lacky carry his shopping, keeping his hands firmly in his pockets.

No doubt the parents of his many legions of young fans would not be too impressed with Bieber's choice of attire. 

With the singer set to celebrate his 18th birthday next year, it seems Bieber taking strides away from his childlike image.

He has an older girlfriend in the form of 19-year-old Selena Gomez and has also been topping up his tattoos recently - bringing his total to three.

The star has just returned from Miami, where he joined his Gomez on her Dream Out Loud tour.

Hinting he has been in a rather romantic mood of late, he wrote on Twitter: 'What makes you so beautiful is that you don't know how beautiful you are... to me.'

He also had a great deal of affection for the city too, adding: 'I LOVE MIAMI.'

Bieber was also spending time with singer Sean Kingston, who recently recovered from a jetski accident.

Bieber describes the star as a 'real friend.'

He is taking a month off to relax with his pals - and of course Selena - before beginning work on his next album.
