The birth certificates for Rumi & Sir Carter have been released to the public and there are quite a few takings from the official documents.
Firstly, we now know who of Beyonce and Jay-Z's twins are the eldest - the winner (not that it's a competition) is Rumi, popping out at 5:13am on June 13. She bet her little brother out of Bey's womb by only mere moments before he was out into the world too.
TMZ's copy of the birth certifcates reveal that the twins were delivered by OB/GYN Dr. Paul Crane, named an entertainment "industry favorite" by the Hollywood Reporter. According to TMZ, Dr. Crane has previously delivered babies for Kim Kardashian, Kourtney Kardashian, and Blac Chyna.
