Look who’s the #proudmama now! Kim Kardashian took to Twitter on Thursday, Jan. 18 to tweet about her son Saint‘s latest milestone — he can spell! According to the reality star, he spelled out “gargantuan,” which is no small feat for a two-year-old!

“Guys I have to say my son is a genius! He’s two years old and knows how to spell gargantuan. Had to brag for a sec!”

Earlier this week, Kim and her husband Kanye West‘s surrogate gave birth to a healthy baby girl — Chicago West! The duo shared the exciting news on her website on Jan. 19.

Kanye, who is from the Windy City, has rapped often about his love for his hometown — but the name is definitely unexpected. Kim previously confessed that the couple preferred one syllable names. “I do like different names. But short, easy to spell, one syllable — that’s kind of my vibe,” Kim told Ellen DeGeneres last year. Last time we checked, Chicago has three.

Fans began speculating over possible options since Kim accidentally confirmed the gender on The Ellen DeGeneres Show in November. “My daughter thinks she’s tricky. We had a baby shower over the weekend, and I thought, ‘You know, I really do want to have a baby shower because I want [North] to feel that something’s coming and for her to really understand it,'” the 37-year-old said at the time. “So, people brought toys and gifts and [North] was opening them all up the next day. And she goes, ‘Mom, since Baby Sister’s not here, I think I need all of her toys in my room and play with them and make sure they’re all okay for Baby Sister.'”

Most recently, fans began wondering if she would be naming her daughter Louis or Vuitton after she posted a seemingly telling snap on Instagram. The photo was a close-up of Louis Vuitton’s classic brown print. There was no caption to explain the purpose of the pic, so of course fans immediately jumped to conclusions. “Are we thinking Louis or Vuitton?” questioned one fan, assuming one or the other would be Baby West’s first name. “Please don’t tell me you called your child LV,” said another, with a third thinking it would be pronounced “Elvie.” (Honestly, that’s cute — and better than Chi.)
