Beyoncé just gave birth to her first child, Blue Ivy, and proud father Jay-Z already has a birthday present for her — a song dedicated to his new daughter, in which he reveals the couple suffered a miscarriage.

In a new song released Monday aptly titled Glory, Jay-Z triumphantly raps to Blue, "Words can't describe what I'm feeling for real… My greatest creation was you."

But the 42-year-old first-time father also reveals the tragedy and trials he and Beyoncé went through before having Blue Ivy, namely a miscarriage.
