They’re here, officially: On Sunday, Mayor Christian Estrosi of Nice, France, presented one of the birth certificates of Angelina Jolie and Brad Pitt’s twins on the steps of Nice’s Fondation Lenval hospital, where son Knox Léon and daughter Vivienne Marcheline were born Saturday. The typed certificate revealed that Knox was born at 6:27 p.m. on July 12. Sister Vivienne came within a minute of that time, Dr. Michel Sussmann tells PEOPLE. The document also showed the Mayor’s signature, as well as Pitt’s initials, the letters WBP representing his full name, William Bradley Pitt. The mayor entered the hospital at 3:24 p.m. to oversee the signing, telling PEOPLE, “It’s a pride to Nice and all its citizens.” Knox is the 3,702 registered birth certificate in Nice for 2008. In welcoming the twins, Estrosi told reporters, “On behalf of the inhabitants of Nice, I congratulate the happy parents, the most famous couple of the world who have chosen our city for this happy event.”

Clearly, the Mayor of Nice is very excited to claim the Jolie-Pitt twins as his own. After the jump, check out a close up of Knox Léon’s birth certificate …
