The proud parents were joined by their eldest daughter, Blue Ivy Carter.Theo Wargo//Getty Images“It feels surreal because my daughter’s here,” Beyoncé told Vogue on the red carpet at the time. “It’s incredible to be able to share it with her.”In March, Jay-Z gushed about his daughter to GQ, sharing how impressed he was with the 14-year-old’s work ethic, especially during her appearances as a backup dancer at Beyoncé’s Cowboy Carter Tour.“That was amazing,” he said. “On the first tour [Renaissance] there was a lot of conversation around her first performance, and she worked really hard to get to that point, but she still wasn’t going for it. She still was going through the motions. And then she just started fighting back. I saw her fight maybe for the first time in her life—like, not everything is just given to her and everything is easy. She fought for it. She’s almost on every number. I had to take her off some, like, ‘Man, you can’t be on that stage when she’s singing “Six-inch heels…,” are you crazy?’”
