Following her comment about daughter Blu Ivy needing a playmate and her MET Ball appearance, rumors began to run wild about Beyoncé concealing a second pregnancy. With the star's recent cancellation of her May 14th concert the singer is making it hard for the public not to wonder.

The "Bow Down" singer canceled her Tuesday concert at the Sportpaleis in Antwerp due to exhaustion and dehydration according to the Huffington Post. Her publicist told the Associated Press that doctors advised the singer to rest.

Beyoncé is scheduled to perform Wednesday at the same arena but the show is undecided seeing as "she is awaiting word from her doctors before making a decision."

Jay-Z's wife first posted about the cancellation on her official Facebook page but did not give any reasons as to why the concert was canceled.

Representatives for the singer did not respond to requests for comment.

Tickets holders should not worry as both the singer and the concert venue said the show will be rescheduled for a future date.

According to the Huffington Post, they did reach out to the 31-year-old's publicist for comment, "but there is a high probability that this is just another empty rumor the Internet has run with."

Earlier this month Beyoncé told ABC News that she wants another child, "I would like more children. I think my daughter needs some company. I definitely love being a big sister. At some point ... when it's supposed to happen."

Beyonce and husband Jay-Z welcomed their first child Blu Ivy into the world back in January 2012.
