But now, according to the infamous gossip webloid MediaTakeOut.com, the former Destiny's Child songstress is definitely expecting. And here's why...

Apparently, Bey has a post "Mrs. Carter World Tour" performance ritual which includes her drinking a single glass of champagne (Ace Of Spades). But after she started touring Brazil, Beyonce suddenly stopped this ritual. Allegedly, she's not drinking any sort of alcoholic beverage before or after performances anymore.

An MTO insider who supposedly works on Bey's tour reveals that they haven't seen the "Bow Down" beauty drink ANYTHING... which is VERY rare ffor Jay-Z's main squeeze.

And for some more baby bump "evidence," MTO has some close-up photos of Bey's Sept. 28 performance at the Coliceo de Puerto Rico in San Juan, Puerto Rico. Check them out here... do they really prove anything?

So what do readers think... are Bey and HOV expecting baby no. 2?
