The media is talking about Beyonce & Jay-Z expecting their second chil. what's fueling this burning question? In April, Beyonce told Shape magazine that they would definitely have more children in the future, saying "I'll probably start after this tour." Her first, Blue Ivy, is 16 months old. She hit the road with her "Mrs. Carter Show World Tour" that month, and will be on the road until September -- but maybe she just couldn't wait. Her appearance at the Met Gala in early May featured her in a "stomach-concealing Givenchy gown," as E! Online described it, and as the site suggested, concealment could only mean one thing. On May 13, the New York Post went into full rumor mode, saying that "music insiders are chattering" about her newly-pregnant status, and noted that photos from her tour seem to reveal a baby bump. On May 14, the singer postponed a concert in Belgium, saying in a statement she was "advised by her doctors to rest as a result of dehydration and exhaustion." She posted a note to her Tumblr page later in apology, noting "I've never postponed a show in my life." Other celebrities like Russell Simmons are already taking the rumors as fact, and tweeting congrats. People are just excited to read about Bey's comings and goings, as indicated by her recent controversial trip to Cuba with Jay-Z and the fact that the announcement of her first pregnancy -- on the 2011 MTV Video Music Awards -- set a Guinness World Record for most tweets per second related to a single event.
