It was a big weekend for Beyonce and Jay-Z (Real name: Shawn Carter)! The couple, who first revealed their pregnancy to the world at the MTV Video Music Awards in August, gave birth to their first child on Saturday night -- a little girl named Blue Ivy Carter. (It was first reported that her name was Ivy Blue, but actress Gwenyth Paltrow later confirmed on Twitter that it is Blue Ivy.)
Although there is no official confirmation of Blue Ivy's arrival, some of the couple's closest friends and family have Tweeted their congratulations! "Welcome to the world princess Carter! Love Aunty Rih," Rihanna wrote. And Beyonce's sister Solange Tweeted, "The most beautiful girl in the world."
