According to a statement from her publicist, Beyonce has canceled her show that was set to take place on Tuesday (May 14) because of dehydration and exhaustion.

Advised by her doctors to rest, this news follows a slew of rumors that the singer is pregnant with her second child. Beyonce will reschedule the show and the tickets previously bought for tonight's show can be used.

Her Mrs. Carter Show World Tour is set to continue today, also at Belgium's Sportpaleis. The concert cancellation comes after last month's news that the singer will ban all photographers from shooting her tour.
