We still haven't gotten a peek at Beyonce and Jay-Z's new arrivals, but recently filed legal documents might just have revealed the babies names.
A trademark document filed this week points to the twins being named Rumi and Sir Carter.
The names are pretty unusual, but in celeb-land unique names are essential.
This also suggests that the pair have had one boy twin, named Sir, and one girl twin, named Rumi.
According to TMZ, the trademarks are for 'fragrances, cosmetics, key chains, baby teething rings, strollers, mugs, water bottles, hair ribbons, playing cards, tote bags, sports balls, rattles and novelty items.'
It would make sense in this case, as Beyonce has previously trademarked Blue Ivy's name.
Five months ago, Beyonce put in a request to the United States Patent and Trademark Office to copyright the term Blue Ivy Carter for future business endeavours.
