Jay-Z was beaming as he hit the stage in NYC Monday evening to kick off his two back-to-back Carnegie Hall shows to benefit the United Way as well as his Sean Carter Foundation. It's Jay-Z's first performance since becoming a dad to baby Blue Ivy Carter in early January and he was looking sharp in his Dolce&Gabbana tuxes. New mom Beyoncé Knowles also stepped out for her first appearance since Blue's arrival, and though she stuck to the sidelines during the show Jay-Z did have some special guests including Alicia Keys and Nas. While fans anxiously await the first glimpse of Blue Ivy, the one month old has already broken records. Jay-Z "Glory," which he wrote and released a day after her birth made Blue the youngest person ever to hit the Billboard charts.
