Beyoncé, Amid Pregnancy Rumors, Cancels Show Due to '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.
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 Beyoncé and husband Jay-Z are expecting a sibling for their daughter, Blue Ivy, now 15 months.
Beyoncé, 31, launched her Mrs. Carter World Tour last month in Belgrade, Serbia. It wraps Aug. 5 at the Barclays Center in Brooklyn, N.Y.
