Beyoncรฉ Knowles has given birth to her first child, a daughter named Blue Ivy Carter.
The baby was born via scheduled caesarean section at Lenox Hill Hospital in New York City on Saturday night.
Beyoncรฉโs husband Jay-Z โ real name Shawn Carter โ was at her side during the birth and mother and baby are reportedly doing well.
The coupleโs close friend Gwyneth Paltrow confirmed the babyโs name on Twitter, posting: โWelcome to the world Blue! We love you alreadyโ.
Gwyneth later clarified the babyโs full name, after a confused Twitter followed enquired about it. โItโs Blue Ivy Carter,โ she wrote.
The babyโs middle name is thought to be in reference to Beyoncรฉ and Jay-Zโs love of the number four.
They both have the Roman numeral for four, IV, tattooed on their wedding fingers.
Beyoncรฉโs birthday is on September 4, while Jay-Zโs is on December 4. Beyoncรฉโs latest album is called 4, and itโs her fourth studio album.
The โBlueโ could be in reference to Jay-Zโs Blueprint trilogy of albums.
Beyoncรฉ, 30, and Jay-Z, 42, married in April, 2008.
