Beyoncé has done herself no favours if she is wanting to end the rumours that she and husband Jay-Z are expecting their second baby together, when the singer dropped out of tonight's (May 14) gig in Antwerp, Belgium at the last minute because of illness. Her uncharacteristic last minute dropping of the show has convinced many that this is proof that Bey already has a bun in the oven.

The official word from camp Knowles is that the 'Crazy In Love' singer is suffering from "exhaustion and dehydration" and has pulled out of the show on her doctor's orders. The singer has a second show at Antwerp's Sportpaleis scheduled for tomorrow, and she has yet to mention whether she will be performing at the follow-up show. If so we might get some indication into what her baby situation is.

The mother of 15 months old Blue Ivy has made no secret of her desire to have more children, and whilst it would make sense for the singer to wait until the end of her Mrs Carter World Tour in August, perhaps the excitement of another baby was too appealing for the broody singer. In a recent interview on US TV, the singer mentioned that that Blue Ivy “needs some company,” and apparently that company can't come soon enough.

The rumours that the singer is pregnant already were first sparked at the Met Gala in New York City, where the singer wore a high-waist, baby bump covering Givenchy dress that set the rumour mill in full motion. If the rumours are true, we're unsure how she'll go about finishing her tour, which will end when she's just about ready to pop.
