NEW YORK (AP) -- Beyonce is canceling her Tuesday concert in Belgium because of dehydration and exhaustion.

In an email to The Associated Press, the singer's publicist says Beyonce has been advised by her doctors to rest. She was scheduled to perform at the Sportpaleis in Antwerp. The show will be rescheduled and tickets can be used at that show.

Her next tour date is Wednesday at the same arena. The statement says "she is awaiting word from her doctors before making a decision."

Beyonce, 31, launched her "Mrs. Carter World Tour" last month in Belgrade, Serbia. It wraps Aug. 5 at the Barclays Center in Brooklyn, N.Y.
