Beyonce Knowles has finally given birth to her first child Ivy Blue Carter at the Lenox Hill Hospital in New York.
Jay-Z went rented the entire entire fourth floor of the hospital for $1.3 million so that the couple could have privacy during the birthing process.
Pop singer and friend to the couple Rihanna tweeted: “Welcome to the world princess Carter! Love Aunty Rih (sic).”
Music mogul Russell Simmons closely followed, writing: “Congrats to my good friends Beyonce and Jay-Z (sic).”
Beyoncé reportedly checked into the hospital under the name Ingrid Jackson and some of her friends were seen bringing bottles of red wine and food to celebrate the birth.
