Madonna has failed to sell out the first night of her British tour.
The singer is performing at Cardiff's Millennium Stadium on July 30, and although most of the cheaper £55 and £70 tickets have been sold, organisers are having trouble selling the more expensive £150 seats.
A tour insider said, "Madonna should be the hottest ticket of the year, but for many of her loyal fans think the prices are outrageous."
The star is charging more than many other big names touring this year, with tickets for the Rolling Stones starting at £40 and Robbie Williams offering seats for £45.
In 2004, Madonna was slammed by Elton John over the quality and cost of her Reinvention Tour. He complained, "Madonna - best f***ing live act? Since when does lip-synching count as live? Anyone who lip-synchs at a show which you pay £75 a ticket to see should be shot."
The tour's promoters have refused to comment on the story.
