Madonna, citing laryngitis, has canceled her sold-out Friday night concert at the Continental Airlines Arena.

No rain date was scheduled for the "Drowned World Tour" show, but the approximately 20,000 ticket holders will receive a refund, her publicist's office said.

Madonna's next show, scheduled for Aug. 7 in Boston, was still on, officials said.

Rachel Keenan cried outside the arena Friday afternoon after finding out the show was canceled. She and her friend Katie Cortese drove to New Jersey from Pittsburgh after buying tickets on the Internet auction site e-Bay.

Ticketmaster phone and Internet orders will be automatically refunded and credited to the card holder within two weeks. Customers who bought tickets at Ticketmaster outlets and the arena box office can get refunds there, according to the Meadowlands Web site.

The Continental Airlines Arena Box Office will begin giving refunds Aug. 6.

For more information, the arena box office's phone number is 201-935-3900.
