Grammy-award winning singer Beyoncé Knowles was forced to cancel her Tuesday appearance in Belgium due to what doctors are calling exhaustion and dehydration.

A statement given to the Associated Press (AP) by the singer's publicist read, "Beyoncé has been advised by her doctors to rest as a result of dehydration and exhaustion and will not be able to perform in Antwerp, Belgium, tonight."

"Tonight's show will be rescheduled as soon as possible and ticket holders should keep their tickets to be used with the rescheduled date. Other tour dates are not expected to be affected."

The concert was to be held at the Antwerps Sportpaleis, which is considered the second most visited venue in the world. The stop was part of Beyoncé's "Mrs. Carter World Tour" that kicked off last month in Belgrade, Serbia and is slated to end Aug. 5 at the Barclay's Center in Brooklyn.

The singer's publicist also told AP the she will await the advice of her doctors before moving forward with any concert dates. The caution taken by Knowles and her medical team has raised suspicions over a second baby on the way.

Knowles and husband Jay-Z recently welcomed daughter Blue Ivy Carter into the world in January 2012. The singer did not comment on the possibility of a second pregnancy.

Tickets for the cancelled show will be used for the rescheduled date that has not been announced as of yet. The next stop on the tour is scheduled for Wednesday in the same venue.
