Luna speaks!

Chrissy Teigen and John Legend's adorable daughter spoke her first word on Monday, which the supermodel mama shared to Instagram with the caption, "So many firsts!"

In the sweet video, Teigen points out a four-legged feline, and in a few seconds, the 11-month-old baby manages to say the word, "Cat."

You did it, Luna!

Though, there may be some discrepancy about what her official first word is.

"I feel like she already said her first word, which is 'hi,'" Legend told ET in January. "Because I feel like she's aware shes saying it, and she waves when she says it, so I feel like that's her first official word."

Either way, she's an amazing little talker!

That wasn't the only first for the famous daughter, either. Teigen shared another pic of Luna with a bow in her hair, writing, "First bow."
