Everything We Know about Beyoncé and Jay-Z's Twins Rumi and Sir Carter Who Will Turn 3 in June

Jay-Z and Beyonce are unarguably the music industry’s most prominent power couple. However, some members of their family are still a mystery to the public.

The couple pretty much has it all: awards, money, and adorable kids. Of course, everyone knows about the couple's first child — Blue Ivy Carter. She has been to the Grammys with her parents, and she's been a fixture in the media.

However, people don't know much about Jay and Beyonce's twins — Sir and Rumi Carter. Beyonce gave birth to the twins in 2017, thus giving their first daughter, Blue Ivy, a pair of adorable younger siblings.

At the time, Queen Bey announced their birth in an Instagram post one month after putting to bed. The post featured Beyonce holding the twins and looking all majestic. She captioned it:

"Sir Carter and Rumi 1 month today. ??❤️?????????"

Even at that, people don't know much about the twins to this day. They've only made a few appearances in the media, and people rarely see them elsewhere.

It could all be on purpose, of course. Pretty much the entire world has come to know about Blue Ivy. Perhaps Beyonce and Jay decided to be more private with their twins for some reason.

There's also the fact that the twins appear to have been born prematurely.

Still, we have been able to find some facts about the children that might interest you. The first, surprisingly, is that they're a boy and a girl.

Several media houses had speculated on the genders of Sir and Rumi for a while. That's how private Jay and Beyonce were about the children. However, when Beyonce announced the birth, her mother, Tina Lawson, had spilled the beans. In an Instagram post, she wrote:

"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."

There's also the fact that Beyonce had to give birth via an emergency C-section. According to reports, she had become swollen due to toxemia and had to stay in bed for over a month.

Due to the health challenges, she elected to have the C-section. While it was a difficult time, Beyonce explained that it helped her to accept her body even more.

Moving on, reports have also confirmed that Jay and Beyonce trademarked their kids' names. They reportedly filed for trademarks on several baby memorabilia — most likely in a bid to produce baby stuff later in the future.
