It seems Blue Ivy will be a big sister soon.

According to E! News, Beyoncé and husband Jay-Z are expecting their second child.

The entertainment channel's website reports multiple sources confirm the 31-year-old superstar's pregnancy.

Rumors that Beyoncé was expecting baby number two were rampant this week following her appearance at the Met Gala in New York.  Critics say her tight Givenchy dress failed to conceal a small baby bump.

The rumors got even more heated when Beyoncé was forced to cancel Tuesday's show on the Mrs. Carter Show world tour in Antwerp, Belgium because of dehyrdration and exhaustion.
