However, rumors that the superstar is pregnant with her and husband Jay-Z's second child were fueled when the "Halo" singer canceled a show for the first time ever in her more than a decade long career.

Bey was following doctor's orders when she canceled her Mrs. Carter World Tour stop in Antwerp, Belgium Tuesday night. The singer was suffering from dehydration and exhaustion, as Beyonce has been working non-stop since January.

The mother of one posted a message to her fans via her Tumblr account:
