The White Stripes have canceled upcoming tour dates "due to health issues."
"Meg White is suffering from acute anxiety and is unable to travel at this time," the duo said Tuesday in a posting on their Web site. "We hate to let people down and are very sorry."
Drummer White and singer-guitarist Jack White are touring to promote their latest album, "Icky Thump."
Shows set for this month in Albuquerque, N.M.; Austin, Texas; San Diego; Inglewood, Calif.; and Berkeley, Calif., have been canceled.
Ticket holders can get refunds at the point of purchase, the Web site said.
Meanwhile, Justin Timberlake has been ordered to rest his voice.
Timberlake's strained voice is the result of his performance Sunday at MTV's Video Music Awards in Las Vegas and months of touring, Jive Records said in a statement Tuesday.
A doctor ordered several days of vocal rest for Timberlake, forcing the 26-year-old singer to miss shows in Sacramento, Calif., on Monday and San Jose, Calif., on Wednesday.
Tour promoter AEG Live has rescheduled the shows for Sept. 23 in San Jose and Sept. 25 in Sacramento.
Timberlake wraps up his FutureSex/LoveShow tour this month.
