It looks like Blue Ivy's baby brother and sister are named Sir and Rumi, at least according to a pretty strong case made by TMZ.

The gossip site reports that the company run by Beyonce and JAY-Z that owns the trademark to their names filed documents on June 26 to secure rights to the names Rumi Carter and Sir Carter.

The same company also trademarked Blue Ivy's name earlier this year.

According to TMZ, the trademarks will apply to a whole laundry list of items including fragrances, cosmetics, baby rattles, water bottles, strollers, keychains, and more.

They also note that Rumi was the name of a 13th-century Persian poet, while Sir is referenced in a popular quote from him that reads:

“Bring the pure wine of
love and freedom.
But sir, a tornado is coming.
More wine, we'll teach this storm
A thing or two about whirling.”
