Grab a mug, because Grandma Knowles is serving up some tea!

Unlike her ex-husband, Tina Knowles has been given free rein to dish on how the Carters are adjusting to life as a family of five. This weekend alone, she's revealed some pretty interesting deets about Beyoncé's bundles of joy.

In a new interview with Entertainment Tonight, Knowles said the family has adjusted well to the "wonderful experience" of the twins' birth — especially Blue Ivy. 

"She's very proud and very excited," Knowles explained. "She's a good big sister, she really is."

Like their big sis, twins Rumi and Sir Carter have pretty unique names — something the Beyhive's been curious about since they were first reported by TMZ in late June.

When asked about the twins' monikers, Miss Tina deferred to Beyoncé and JAY-Z, saying the couple will reveal the names' meaning in due time. But to the Hive's delight, Knowles ended up shedding some light on the name "Rumi" this past Saturday:

Knowles shared some lines of poetry written by the 13th century poet Rumi on Instagram, calling the excerpts "not only beautiful but logical."

Knowles revealed that the third stanza was her favorite, explaining that "Sometimes we are the reason we can't find love!! We have to work on ourselves first to be whole"

Given Beyoncé's collaboration with poet Warson Shire on Lemonade, it's no surprise that she chose to name her newborn daughter after a poet. 

Now that we've got "Rumi" covered, why do you think Bey and Jay chose "Sir"? Let us know your theories!
