Baby Blue Ivy (or Ivy Blue depending on the source) is the first child for Beyonce, 30, and Jay-Z, 42, who married in April 2008.
Rihanna was one of the first of the star’s friends that tweeted her congratulations, writing, “Welcome to the world princess Carter! Love Aunty Rih.”
Russell Simmons also tweeted, “Congrats to my good friends Beyonce and Jay Z,” while Sean ‘Diddy’ Combs added, “Congrats to Jay and B! God Bless… And many more!”
Actress Gwyneth Paltrow tweeted this morning, “Welcome to the world, Blue. We love you already.”
A “confused” fan asked if the baby’s name was “Ivy Blue or Blue Ivy,” and Gwyneth replied, “It’s Blue Ivy!’
GMA reports the couple chose the name “Ivy” because of the significance of the number “4″ or “IV”.
Both Beyonce and Jay-Z were born on the fourth day of their birthday months and were married on April 4, 2008. Beyonce’s album is also titled “4″.
Congrats to Beyonce and Jay-Z on their baby daughter!
The couple rented out the entire fourth floor of Lenox Hill Hospital for their daughter’s birth, reportedly splashing out $1.3 million for the privacy.
Sources revealed Beyonce checked in on Friday night under the name “Ingrid Jackson.”
The security cameras were taped and hospital staff had to turn in their cell phones to keep unauthorized photos from being released.
