Beyonce and Jay-Z may have indirectly revealed the names they chose for their new twins. TMZ reports that on Monday, soon after the twins were reportedly released from the hospital, the company run by the famous couple (which already owns the trademarks to their names and which filed to trademark the name Blue Ivy Carter earlier this year) filed legal documents to secure rights to two more names: Rumi Carter and Sir Carter. As TMZ notes, Rumi is the name of a 13th-century Persian poet, and the word "sir" is included in one of his best-known poems. (Jay-Z appears to admit to infidelity on his new album.)
