Beyoncé blames 'dehydration and exhaustion' as she cancels Belgium concert amid pregnancy rumours

Beyoncé is canceling her concert in Belgium because of dehydration and exhaustion.

In an email to The Associated Press, the singer's publicist says Beyoncé 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.

The singer blamed the cancellation on 'dehydration and exhaustion' and said her doctor had advised her to rest.

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

The cancellation comes amid reports the 31-year-old is expecting her second child with husband Jay Z.
