Birth Details About Beyonce And JAY-Z's Twins Revealed

Days after Beyoncé and JAY-Z celebrated one month since their newborn twins' arrival, revealing their adorable names, even more information has come out about the babies' births.

According to E! News, Beyoncé's daughter Rumi and son Sir both entered the world at 5:13 a.m. on June 13, 2017, though Rumi was born first by mere seconds.

And, unlike their big sis Blue Ivy, Rumi and Sir have just first and last names—no middle names!

As Nicki Swift previously reported, Beyoncé's mother, Tina Knowles Lawson, opened up about how the Carter family has been since the addition of the twins. "It's exciting. It's a wonderful experience," she said on July 15, adding that Blue Ivy is already "a good big sister."
