Melbourne, Nov 13 Britney Spears' Melbourne gigs are heading for the rocks it seems, as hundreds of tickets of her shows are available on eBay for as low as 99c.

The sell-off by fans comes after it was reported that Britney was lip-synching in her concerts.

Her Rod Laver Arena show on Wednesday was a complete flop with some fans even demanding their money back.

Some were even offering to give away premium tickets outside the venue.

The show was promised to be "a dazzling display of music, dance, magic and theatrics", but with a lacklustre performance and tickets priced between 200dollars and 1500dollrs fans cheated.

"If you're going to mime, at least learn how to dance.... It was the worst $200 I've ever spent," the Herald Sun quoted, a fan as saying.

Independent ticket broker Shaun Black said: "It has been really tough. I will lose a lot of money with this tour.

"But it's not just my tickets that aren't selling, people are just deciding they don't want to go."

He added: "The market has been flooded with people wanting to offload their tickets and now there's just too much supply.

"There were more than 300 tickets listed for Britney on eBay the other day - I have never seen anything like it.

"But no one wants to go."

Although, Britney kept mum about Wednesday, her manager Adam Leber said: "Britney rocked it in Melbourne last night!"

Spears will croon at Rod Laver Arena tonight before leaving for Sydney and will perform at Melbourne on November 27 for the last show.

Even tickets for the Brisbane leg of her tour have been slashed to a mere 50dollars to pep up sales. (ANI)
