As in, she gets to go onstage — or at least right next to the stage, ferried by a large bodyguard who makes her as tall as the adult audience members. Blue Ivy — with requisite noise-canceling headphones — shows up around the 6:00 mark of this London “Irreplaceable†performance, and if you don’t blink, you’ll see Beyoncé reach out and hold her hand. Then Blue Ivy floats away, presumably to beat Jay-Z in a game of Candyland. (That is what all famous babies do while their moms are onstage, right?)
