Beyonce, Jay-Z Issue Statement Welcoming New Baby

On Saturday reports began to trickle in that Beyonce had checked into Lenox Hill hospital in NYC to give birth, and confirmation came early on Sunday that the 30-year-old star was a proud new mother. Friends and even family members--namely Beyonce's sister Solange--tweeted their congratulations, but the couple didn't issue an official statement until late on Monday (January 9). "Hello Hello Baby Blue," the Carters said in a statement to MTV News. "We are happy to announce the arrival of our beautiful daughter, Blue Ivy Carter, born on Saturday, January 7, 2012."

Since the baby's birth was first reported, late Saturday night, there was some confusion over her name. Some reported Ivy Blue Carter, but the couple's official announcement should clear up any lingering doubts.

The typically private Bey and Jay also provided some more intimate details surrounding the delivery of their bundle of joy. "Her birth was emotional and extremely peaceful, we are in heaven. She was delivered naturally at a healthy 7 lbs and it was the best experience of both of our lives," they wrote, putting to rest rumors of a scheduled C-section.

Baby Blue is just three days old, but already the youngest Carter has made her musical debut on "Glory," a dedication track that Hov released Monday on his Life and Times blog. At the close of the Pharrell-produced song, Blue Ivy can be heard crying and cooing, riding alongside her multiplatinum poppa.

It's been a long road, which publicly began August 28 at the MTV Video Music Awards, when Bey revealed to the world that she was pregnant. There have been many well-wishes, much speculation and a ton of curiosity surrounding the birth of the couple's daughter. Now that Blue Ivy Carter is finally here, the Carters even took time to thank the fans.

"We are thankful to everyone for all your prayers, well wishes, love and support," they wrote.
