Looks like Blue Ivy will be having a sibling sooner than we thought.

Beyonce is apparently pregnant with her second child, a source tells E! News.

Rumors have been swirling for the past few weeks about the singer's pregnancy. No official word has come from her camp but recent photos showing a protruding belly -- out of character for the usually slim and trim star --- and a show cancellation in Antwerp, Belgium -- doctors ordered her to rest due to "dehydration and exhaustion" -- further fueled the talk that she was indeed expecting a new bundle of joy.

It's no secret she and husband Jay-Z like to keep their affairs private. After all, it took them years to reveal to the public that they were in fact married. But with this recent confirmation, it's likely the couple will make an official announcement soon.

Currently, Beyonce is performing on her Mrs. Carter Show World tour. The U.S. leg of the performance trek hits L.A. on June 28. No word yet on if this pregnancy will change her tour schedule.
