It appears that Blue Ivy has a little brother and sister. Multiple celeb outlets—including People, US Weekly, and E! Online—are reporting that Beyonce has given birth to twins. While there's no confirmation yet from Beyonce or Jay Z, Beyonce's dad celebrated the news on Twitter. "They're here!" he wrote on a photo of balloons, signing it, "love granddad." TMZ reports that the new boy and girl actually arrived on Monday, but doctors have kept them in the hospital because of an unspecified "minor issue." The site says, however, that the twins and their 35-year-old mom are all expected to be fine. (More Beyonce stories.)
