Beyoncé and Jay-Z's twins' names revealed

Jay Z and Beyoncé have reportedly named their twins, and their monikers are as show-stopping as their parents.

The music moguls are believed to have name the babies Rumi and Sir Carter, according trademark documents filed to the United States Patent and Trademark Office on Monday that were obtained by People. The twins are believed to be a boy and a girl. Beyoncé, 35, reportedly gave birth within the last few weeks.

TMZ reported that Beyoncé and Jay-Z’s company has filed documents to trademark the names for products including fragrances, cosmetics, baby gear, tote bags and water bottles.

As TMZ reported, Rumi shares a name with the 13th century Persian poet. Sir is referenced in one of his most famous poems:

"Bring the pure wine of

love and freedom.

But sir, a tornado is coming.

More wine, we'll teach this storm

A thing or two about whirling."

In the titular track, the 47-year-old entertainer admitted to having an affair and taking his 15-year relationship with Beyoncé for granted. He hit on how he gained perspective from becoming a father to daughter Blue Ivy, 5, and his newborn twins.

He said: "I apologize often womanize / Took for my child to be born / See through a woman’s eyes / Took for these natural twins to believe in miracles / Took me too long for this song / I don’t deserve you," appearing to confirm the twin babies were conceived naturally.

He also suggested that his wife had suffered from miscarriages in recent years.

"So I apologize / I’ve seen the innocence / Leave your eyes / I still mourn this death / I apologize for all the stillborns / ‘Cus I wasn’t pressing / Your body wouldn’t accept it," he continued.
