American superstar couple, Beyonce and Jay Z who are currently bonding with their twins and their daughter Blue Ivy at a Malibu Mansion, have finally named their twins which they welcomed earlier this month.

According to E! News, Beyonce and Jay-Z named the boy and girl ‘Sir and Rumi Carter’.

According to the docs, first reported by TMZ, Beyonce and Jay-Z’s trademarking team has filed the legal documents to secure the rights to the names Rumi Carter and Sir Carter.

The trademarks could be used for products like fragrances, cosmetics, key chains, baby teething rings, strollers, mugs, water bottles, hair ribbons, playing cards, tote bags, sports balls and rattles and novelty items.

Just last week, Beyonce’s team hit a setback in trademarking the name of her and Jay-Z’s first child, Blue Ivy.
