Allow them to introduce their twins.

After much speculation and anticipation, Beyoncé and JAY-Z’s twins’ names have been revealed as Rumi and Sir, according to TMZ.

The billion-dollar couple reportedly filed legal documents to trademark the names Rumi Carter and Sir Carter for their girl and boy, who were born on Monday (June 12).

The trademarks are wide-ranging, including trademarks 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.

If those are their names, Rumi and Sir will be joining their five-year-old big sister Blue Ivy as part of the Carter family. However, JAY-Z and Beyoncé have not officially announced the baby names yet.
