One of the biggest fandom-related events of 2012 has finally arrived! Beyoncé has given birth to a baby girl! [UPDATE: We’ve got the official name!]

People close to Beyoncé and Jay-Z (including Rihanna) have been cryptically tweeting and it looks like the A-list super stars have welcomed their first child, a baby girl, in to the world!

No word on what the name of their daughter is yet, but as soon as we know for sure we will be the first to report it!

UPDATE: They have named their daughter Ivy Blue Carter.

Sources have speculated that Ivy is derived from IV, the Roman numeral for four. The couple was married on April 4, have been married for four years, and Beyoncé’s latest album is titled 4.

UPDATE 2: Beyonce’s child’s name is actually Blue Ivy Carter – not Ivy Blue. There was confusion late last night on Twitter.

Beyoncé and Jay-Z reportedly paid $1.3 million to rent out the entire fourth floor (another IV connection) of New York’s Lenox Hill hospital on Saturday, where Ivy was born by C-section.

Congratulations Beyoncé and Jay-Z!
