How cool it must be to have a rockstar mom! While performing in London this weekend past, the chart topping mega voice, Beyonce, brought her toddler, Blue Ivy on stage while performing her hit “Irreplaceable.” While the moment was brief, it was precious! Little Blue was toted through the crowd on the shoulders of the Carter’s security guard, Julius, wearing a dress and protective headphones. In the video below around the 5:45 mark you can see the sweetest Mom and daughter moment ever!
