It sounds like Beyoncé and Jay Z have named the twins.
According to TMZ, the A-listers have chosen the monikers Rumi Carter and Sir Carter for their newest additions.
Reportedly, the Grammy Award-winning singer, 35, and the rap superstar, 47, had trademark documents filed to the United States Patent and Trademark Office on Monday.
The couple’s company has filed papers to trademark the names for everything from fragrances and cosmetics to baby gear, tote bags and water bottles.
The news comes hours after Jay Z dropped his latest album 4:44, in which he reveals on the title track that the twins were naturally conceived.
“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,” he says.
The newest members of the Carter family – who are reportedly a boy and girl born on June 12 – join 5-year-old big sister Blue Ivy. The family of five are currently living in a $400,000-a-month Malibu rental.
