Beyoncé and Jay Z appear to have named their twins — or at least the company that trademarked Blue Ivy Carter's name has applied to trademark "Rumi Carter" and "Sir Carter," so that's a pretty big clue.
The applications were filed Monday on behalf of BGK Trademark Holdings and, according to the U.S. Patent and Trademark Office database, are still being reviewed. They seek to identify Rumi Carter and Sir Carter in connection with a host of items including recordings of musical performances, books, flags, sports gear, clothing, hair accessories, beauty products such as cosmetics and fragrances, entertainment services and, of course, baby products.
Plus key chains and mugs. Never forget the key chains and mugs.
