The tiny tot's cries are featured on new Jay-Z track 'Glory', where the proud papa raps about his little girl's birth.
Jay-Z uploaded the track to his website, where Blue Ivy is credited as 'B.I.C'.
"The most amazing feeling I feel, words can't describe what I'm feeling for real," he raps on the track.
"Baby, I paint the sky blue, my greatest creation was you."
He also hilariously namedrops Beyonce's former girl group: "You're the child of destiny / you're the child of my destiny / you're my child with the child from Destiny's Child."
In a shock move, Jay-Z also reveals Beyonce had previously suffered a miscarriage.
"Last time the miscarriage was tragic / We was afraid you'd disappear but nah baby you're magic," he rapped.
