Jay-Z Raps About Birth Of Daughter, Reveals Miscarriage In 'Glory'

NEW YORK (CBSNewYork/AP) -- Through a rap verse, Jay-Z has confirmed the birth of "the most beautiful girl in the world" -- his newborn daughter.

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

Reps for the superstars repeatedly declined requests for comment from The Associated Press about whether the birth had occurred, as first reported by E! News. But Jay-Z's sweet song gives fans the details, and more: "You're my child of a child from Destiny's Child."

In the song, Jay-Z talks about where the child was conceived (in Paris) and even reveals that Beyonce had a miscarriage at one point.

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

The sound of a baby's cries ends the song.

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."

Meanwhile, the birth of the new baby left others fuming on Sunday. Some patients that shared the hospital with Blue Ivy Carter say her birth kept them from seeing their own newborns in intensive care.
