Sources close to Beyonce confirmed to E! News on Friday that the singer is pregnant with her second child with husband, rapper Jay-Z.

Speculation began last week when a photo of the singer on stage in London with a bit of a tummy bulge circulated throughout the blogosphere. When Beyonce cancelled her show in Belgium due to "dehydration and exhaustion," that only fueled the rumors.

News outlets upon news outlets are sending well wishes to the happy family. But today's announcement also leaves many fans wondering what this means for Beyonce's world tour, which was set to last through September. There's no word yet from Beyonce's camp on the tour, but based on her recent cancellation, it may be tough.

Doctors recommend that expectant mothers don't fly after 36 weeks into their pregnancy. That time period can be shortened (but never lengthened) based on the health of both the baby and the mother. So depending on how far along Beyonce currently is, her pregnancy could interfere with her travel to some of the later shows on her tour.

And even if she can travel, will fans get the same kind of show that they would if she was not pregnant? Probably not.

Some of the symptoms of pregnancy are enough to make a woman working a desk job call in sick to work. The fatigue, nausea, back aches, and breast tenderness would not be easy to deal with on stage in front of thousands of screaming fans every night. And, not to be outdone, the double whammy of constipation and the constant urge to urinate would be extremely uncomfortable to have to dance, sing, and twirl through.

For now — since Beyonce hasn't confirmed the pregnancy herself — let's just assume the show will go on.
