No wonder it’s taken so long to learn the names of the Jay-Z/Beyoncé twins. You have to get their names trademarked, right?

And if that isn’t their real names, at least new product lines are covered.
“The trademarks are for fragrances, cosmetics, key chains, baby teething rings, strollers, mugs, water bottles, hair ribbons, playing cards, tote bags, sports balls and rattles and novelty items,” TMZ says.
The Daily Mail adds: “While both names are distinctly unusual choices, Sir is the more uncommon of the two – with the name normally used as a title before a man’s first name. Meanwhile Rumi is a Japanese girls name, and also the last name of the famed 13th century Persian poet Jelaluddin Rumi.”
Early reactions:
Rumi and Sir Carter. Okay. I was rooting for Brooklyn and Houston.
