The high ticket prices don't seem to put hardcore Madge fans off - ticketlines are jammed and websites frozen due to the astonishing demand...

Phonelines are jammed and websites frozen this morning (April 26) as thousands of fans attempt to get tickets for MADONNA‘s LONDON shows in July.

And three additional dates which had been added have sold out within minutes of going on sale.

Ticket agent Ticketmaster said that their website crashed this morning as thousands of people logged on in a bid to get tickets for the show on July 6, which went on sale at 8am.

At the time of writing, their phonelines were inaccessible, and when NME.COM contacted them this morning an assistant said that there were 472 calls presently on hold.

“We announced a fourth date, on July 9, four minutes ago and it’s just about sold out,” she added.

Madonna-mania began two days ago, with fans travelling from as far away as Edinburgh to start queuing for tickets, and ambulance and police staff were on call at Earl’s Court, where a massive queue built up overnight of people eager to shell out up to £85 for tickets.

The queen of pop will now appear at Earl’s Court on July 4, 6, 7 and 9, and according to sources a further two dates may be announced to meet the overwhelming demand.

The star’s ‘Drowned World’ tour kicks off on June 5 at Cologne Arena, in Germany.
