Shortly after Beyoncé posted her instantly iconic baby photograph on Instagram on Friday her mom Tina followed suit. Unlike Bey, grandma Tina added a little extra information with her post and confirmed that Sir and Rumi are, for the record, a boy and a girl.
"So Happy my baby shared a photo of her babies with the world ❤️❤️❤️proud grandma hello Sir Carter and Rumi Carter❤️🙏🏾❤️ Boy and girl what a blessing ❤️," she wrote in her caption.
Reports that Beyoncé had given birth to the twins circulated on June 17, though Bey's Instagram post confirmed that their birth date was between June 13 and 14. The names of Beyoncé and JAY-Z's twins were first reported after the parents filed trademark licenses for the names Sir and Rumi Carter on June 26.
According to the United States Patent and Trademark Office website, the trademarks were filed by BGK Trademark Holdings, Beyoncé's holding company that also owns the trademarks for the name Beyoncé, Beyhive, and Blue Ivy Carter.
