The song "Glory" made its debut on his social website Life and Times on Monday, two days after he and wife Beyonce gave birth to daughter Blue Ivy.

An official statement from the couple came Monday afternoon, as both said, "We are happy to announce the arrival of our beautiful daughter, Blue Ivy Carter."

The couple said the baby was delivered naturally and weighed 7 pounds. "Her birth was emotional and extremely peaceful, we are in heaven. ... It was the best experience of both of our lives. We are thankful to everyone for all your prayers, well wishes, love and support."

Jay-Z's sweet song, in which he says, "You're my child with a child from Destiny's Child," gives more revelations.

In the song, Jay-Z , whose real name is Shawn Carter, talks about where the child was conceived (in Paris) and even reveals that Beyonce had a miscarriage earlier.

"Last time the miscarriage was so tragic/We was afraid you'd disappear/But nah baby you magic."

The song's refrain is: "The most amazing feeling I feel/Words can't describe what I'm feeling for real/ Maybe I paint the sky blue/My greatest creation was you. You. Glory."

The sound of a baby's cries — perhaps Blue's — ends the song. The song says it features "B.I.C.," Blue's initials.

It's the first child for the power couple, who wed in 2008 in a private ceremony after a years-long courtship. Beyonce announced her pregnancy to the world last August at the MTV Video Music Awards with a simple rub of her swollen belly.

Celebs close to the couple have tweeted congrats. Beyonce's sister, Solange Knowles, tweeted Sunday morning, "The most beautiful girl in the world," while Beyonce's close friend Gwyneth Paltrow also tweeted, "Welcome to the world Blue! We love you already."

The couple gave birth at Lenox Hill Hospital on New York's Upper East Side on Saturday. In a statement released Monday by the hospital's executive director, Frank Danza, he said the hospital was "delighted" to have the couple deliver their child there but that its staff is "troubled by the misinformation being circulated in some news media reports."
