Beyonce Pregnant Scare? Cancels 'Mrs. Carter Show' Belgium Concert for 'Dehydration, Exhaustion' amid Baby Bump Rumors [PHOTOS]

Rumors are currently swirling on the web that former Destiny's Chid songstress Beyonce is pregnant with baby number two - and those rumors were only hightened on Tuesday (May 14) when Queen Bey announced that she had to cancel her highly-anticipated "Mrs. Carter Show" concert in Belgium. B's publicist told the Associated Press that the starlet was suffering from "dehydration and exhaustion," but could it be Beyonce's growing baby bump that's made her suddenly fall ill? Usually these "celebrity baby bump" sightings are totally bogus, but considering Bey and Jay-Z claim that they'd love to have more children sometime soon, such pregnancy buzz is becoming harder to ignore...

For some background on the Beyonce baby bump gossip... as originally noted by Mstars:

In a recent interview with ABC's Amy Robach during a break from her Mrs. Carter Show World Tour in London, Queen Bey admitted that she definitley wants more children, especially since baby Blue Ivy could "use the company." Of course this only helped to refuel such pregnancy rumors...MediaTakeOut claims it even has the baby bump pics to prove it. Do fans really think the "Single Ladies" songstress is preggo with Jay-Z's second baby? Allegedly the couple's currently preparing to make an official baby announcement... at next month's BET Awards!

Apparently, a "qualified" inside source recently confirmed to MediaTakeOut that Beyonce is indeed pregnant. She's allegedly already two months along - she's hoping to hide her "baby bump" from the public's eye until she's out of her first trimester (which is why she's not allowing ANY outside photographers to snap pics during her current concerts and performances). "Only photos that do not show her stomach up close are released to the public," the insider explains.

And here are MediaTakeOut's baby bump pics to "prove" it.

In a recent interview with Amy Robach, Beyonce talked about family and how she'd like to expand the love one day:

"I would like more children. I think my daughter needs some company. I definitely love being big sister [to Solange Knowles]."

Bey goes on to explain that her life's "completely different" since becoming a mom to baby Blue Ivy - but in an awesome way. She's grateful that her life now has "way bigger meaning." She's hoping that she can provide Blue with a fullfilling life... with the love and support of additional siblings (one day):

"I am very protective. I just want to make sure that she can have a healthy, safe, normal life... At the end of the day, you're the exact same person. I still like the simple things."

Now, apparently photos from the annual Met Gala ball in NYC PROVE that Bey's indeed expecting:

What do fans think, is that a tiny baby bump underneath that bulky belt?

Page Six of the New York Post allegedly CONFIRMS such baby bump rumors:

"Multiple sources told us after the Met Gala last week that the singer, who is currently in the middle of a world tour, is pregnant."

Even so, several other gossip outlets insist that fans shouldn't necessarily expect a Queen Bey/Jay-Z little bundle of joy anytime soon. A source tells People, "Beyoncé and Jay are planning for another baby after her tour is over and things calm down just a bit."

Now there's the fact that Beyonce suddenly cancelled her schedule tour performance in Belgium on Tuesday evening. She posted this message on Facebook:

Beyoncé: "Belgium... Unfortunately tonight's show has been canceled... Please keep your tickets for the rescheduled show... Our sincerest apologies for the late notice and stay tuned for the new show date announcement."

So what's the deal - is it truly exhaustion and dehydration, or a bout of morning sickness?

Bey and her reps have yet to comment on the pregnancy rumors, but Bey's publicist claims they're waiting on "doctor's orders" to see about Wednesday's performance (also in Belgium).

So what do fans think about the baby bump rumors?

Beyonce's tour will conclude in Brooklyn, NY on Aug. 5... so stay tuned for further details!
