Blue Ivy Carter wasn't the first baby inside Beyonce's belly.

According to her husband, Jay-Z and his new song, Glory, Beyonce, 30, had a miscarriage long before the couple proudly announced their pregnancy last August.

False alarms and false starts / All made better by the sound of your heart . . . Last time the miscarriage was so tragic / We was afraid you'd disappear / But nah, baby you magic, Jay-Z raps on the track, which was released on Monday.

In the song, Jay-Z, 42, also reveals where baby Blue was conceived.

Daddy's little girl / You don't yet know what swag is / But you was made in Paris / And mama woke up the next day / And shot her album package, according to the rapper.

The most amazing feeling I feel, words can't describe what I'm feeling for real / Baby I'll paint the sky Blue / My greatest creation was you, the proud papa continues, adding that Blue is a pinch of Hov and a whole glass of B.

Glory, which was recorded just hours after Blue's birth at Lenox Hill Hospital on Saturday, also features the cries of Blue herself, who is credited as B.I.C. (fast forward to the track's last 30 seconds).

In honor of the birth of his daughter Blue Ivy Carter, new father JAY-Z has released the track 'GLORY' featuring B.I.C., Jay-Z's music and entertainment company Roc Nation posted on its Web site, along with a photo of the Empire State Building in blue lights.

Since the release of Glory on Monday afternoon, Twitter feeds have been exploding with the hashtag #Glory and reaction from fans.
