Beyonce cancels show under doctor's orders

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 said "she is awaiting word from her doctors before making a decision."

The news comes as reports surface that Beyonce could be pregnant with her second child. Multiple sources told The New York Post that Beyonce is pregnant, but there's been no comment from the singer or her publicist.

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.
