However, thanks to Tina Knowles and her entertaining Instagram account, we have some insight. Firstly, B's mom clarified for us that the babies names are Sir Carter and Rumi Carter, not, as some had assumed, Sir Carter Carter and Rumi Carter. And for anyone questioning the gender of the twins, Tina confirmed once and for all that they are a girl and a boy.

The new grandmother also explained the meaning behind the name "Rumi." She shared a selection of quotes from the 13th-century Persian poet by the name of Rumi, highlighting in the caption that it's good to be not only beautiful but logical.

"Love number three… Sometimes we are the reason we can't find love!! We have to work on ourselves first to be whole," Tina wrote.

This isn't the first time Beyoncé has taken inspiration from a writer. The singer famously collaborated with British poet Warsan Shire on her album Lemonade and sampled Chimamanda Ngozi Adichi's TED talk "We Should All Be Feminists" in her song, "Flawless."

We can't wait to see more of Sir and Rumi!
