“Welcome to the world princess Carter!” Rihanna tweeted. “Love Aunty Rih.” Meanwhile, rap mogul Russell Simmons wrote, “Congrats to my good friends Beyonce and Jay-Z.”

So what would the superstar couple name their already famous baby girl? Like most things Jay and Beyonce, the newborn’s name is a mystery. Earlier, sources told E! News her name is Blue Ivy Carter, while others told TMZ its Ivy Blue. Beyonce’s BFF Gwyneth Paltrow cleared up the confusion by tweeting that the baby’s name was Blue Ivy after all.

The Grammy winner, 30, and hubby Jay-Z are said to have checked into Lenox Hill Hospital in New York’s Upper East Side on Friday night under the alias Ingrid Jackson, where Beyonce underwent a scheduled C-section, reports the New York Daily News. The couple reportedly rented out the entire 4th floor of the hospital for $1.3 million.

Beyonce made her last public appearance on Thursday, when she was photographed running errands with mom Tina Knowles.

False rumors of Beyonce giving birth during Christmas week had the Internet ablaze. But eyewitnesses said they spotted the heavily pregnant singer enjoying a New Year’s Eve dinner at one of her favorite restaurants, Buttermilk Channel restaurant in Brooklyn, with hubby Jay-Z.

Never letting her pregnancy slow her down, Beyonce was constantly photographed running her errands in New York City. She even released five music videos since announcing her pregnancy at the 2011 MTV Music Awards.

Though Beyonce has kept the real date of her delivery a secret, according to a behind-the-scenes video she posted in which she says she is six months pregnant back in September, she was due to give birth in December or January.

We wish the happy mom a beautiful recovery, and can’t wait to meet her and Jay’s bundle of joy!
