Music insiders are chattering about Beyoncé expecting her second child with husband Jay-Z. Multiple sources mentioned after the Met Gala last week that the singer, who is currently in the middle of a world tour, is pregnant. Bey wore a Givenchy gown with a high, belted waist that carefully camouflaged her midsection, but pictures have emerged on blogs of what looks like a baby bump from recent tour dates. Last week Beyoncé, who gave birth to daughter Blue Ivy in January 2012, gave an interview to ABC’s “GMA,” where she said, “I would like more children. I think my daughter needs some company. I definitely love being a big sister.” But she came short of saying when that would occur: “At some point, when it’s supposed to happen,” she told ABC’s Amy Robach. Beyoncé’s rep didn’t get back for comment. But we wouldn’t expect her to — the singer announced she was pregnant with Blue Ivy at the 2011 MTV Music Awards by revealing her bump on the red carpet.
