Jay-Z is such a proud parent! In a newly released commercial for his album Magna Carta Holy Grail — which drops tomorrow — the rapper gushes about baby daughter Blue Ivy Carter and even gets close to shedding tears. Speaking to producer Rick Rubin, Jay talks about his and wife Beyoncé's love for 18-month-old Blue, saying that she's "something that we both made. We still marvel at her." He goes on to explain the inspiration for the track "Jay Z Blue" and reflect on the shortcomings of his own dad, who left when he was young, and gets especially choked up when revealing his worries about parenting, saying, "I have a daughter. It's the paranoia of not being a great dad."
