Madonna [ tickets ]'s Friday night (8/3) concert at the Continental Airlines Arena in East Rutherford, N.J., has been canceled, promoter Clear Channel Entertainment announced. According to the artist's management, she is suffering from laryngitis.

The canceled show--which will not be rescheduled--was to have been Madonna's seventh sold-out performance in the New York area. The decision not to reschedule immediately drew an angry response from fans posting on her official website.

"I think it's absolutely ridiculous that she didn't re-schedule the concert," one fan wrote. "I think it's safe to say that she alienated a lot of her fans for not being willing to move the show to a later date."

All Ticketmaster phone and Internet orders will be automatically refunded and credited to the card holder within two weeks, according to a press release. Tickets purchased at Ticketmaster outlets and at the Continental Airlines Arena box office will be refunded at the point of purchase. (Ticketmaster is liveDaily's parent company.)

Madonna [ tickets ]'s tour is expected to resume in Boston on Aug. 7 and 8.
