RAPPER Jay-Z yesterday released a song for newborn daughter Blue Ivy — and revealed wife Beyonce previously had a miscarriage.

On the track, called Glory, he raps: "Last time the miscarriage was so tragic, we was afraid you disappeared." He also talks of "false alarms and false starts" but calls Blue — born on Saturday — as "my greatest creation".

Last night reports in the US said other new mums were unhappy with their treatment as security was upped for Jay-Z, 42, and Beyonce, 30, and may sue New York's Lenox hospital.
