After all the confirmations and information from friends and relatives, now Beyonce and Jay-Z themselves have confirmed the birth of their baby Blue Ivy Carter.

American singer Jay-Z released an official statement declaring the arrival of their beautiful daughter yesterday.

The statement was released on Beyonce's official Web site on Jan. 9 and clarified all the confusions about the baby's name and other details.

According to the statement, Beyonce delivered at Lenox Hill hospital, NYC, on Jan. 7, 2012. Both the baby and mother are doing well. Baby Carter weighs 7 lbs and is healthy.

The delighted parents thanked fans, friends and all others who had prayed for them and made it the best experience of their lives.

Meanwhile, Baby Blue's hip-hop father Jay-Z released his new song that discloses several other private details of the baby's birth. It is a beautiful description of the feelings of a first-time father and how the baby was born, when she first cried and the whole experience in a rap song.

In honor of the birth of his daughter Blue Ivy Carter, new father JAY-Z has released the track 'Glory,' Jay-Z's music and entertainment company said in a statement on their Web site.

In the song Glory, he also reveals that the baby was conceived in Paris.

Here are the lyrics, 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.

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.

Jay-Z refers to baby Blue Ivy Carter as B.I.C in the rap song that was recorded just hours after her birth at the hospital itself.

Here is a transcript of a joint statement released by Jay-Z and Beyonce.
