【Lady Moon】

Sound the clarion horns,Lady Moon the royal twins are Instagram Official.

Beyoncé posted a photo of herself with the baby boy/girl twins on Thursday night -- after 10 p.m. Pacific! -- confirming in her caption that their names are indeed Sir Carter and Rumi.

No Peoplemagazine cover sale, no carefully planned, news-cycle friendly launch before the morning news shows. At 10:10 p.m. on Thursday, July 13, in the 2017th year of our Lord, Beyoncé decided that it was time to show you something.

Sir Carter and Rumi 1 month today. 🙏🏽❤️👨🏽👩🏽👧🏽👶🏾👶🏾

Not hard to spot here is the thematic call-back to her pregnancy photo, which Beyoncé dropped in February, along with the news that she was carrying not one, but two baby Bey-Zs.

We would like to share our love and happiness. We have been blessed two times over. We are incredibly grateful that our family will be growing by two, and we thank you for your well wishes. - The Carters
