After getting candid earlier this year about her struggle with postpartum depression following the birth of her daughter Luna, Chrissy Teigen is pregnant with her second child, according to Romper. In June, the 31-year-old Teigen opened up to Marie Claire about her and husband John Legend’s desire to have more children.

The couple has been open about their infertility issues and hopes to have a big family. Teigen told Marie Claire, “I love John and Luna more than I can imagine loving anything, and John and I still hope to give Luna a few siblings.” In the November issue of InStyle, Teigen revealed that she and Legend would attempt to have another child via IVF with their last remaining frozen embryo in the coming months.

Teigen made the adorably sweet pregnancy announcement in a video posted to her Instagram account. In the short clip, Teigen can be heard asking 19-month-old Luna “What’s inside?” while pointing to her belly. In the cutest little voice ever, Luna says with a smile, “Baby!” It seems like Legend can be heard giggling off-camera in the background. Teigen playfully captioned her Instagram video with, “It’s John’s!”

it's john's!

While there’s no official word yet on when we can expect to meet Luna’s little sibling, fans might have an inkling about whether she’s getting a little brother or a little sister. In January, at the 28th Annual Producers Guild Awards, Teigen told Entertainment Tonight that they wanted to give Luna a little brother. “A little boy is next, for sure,” she said.

Given that the couple went through a sex selection process during their first IVF cycle, there’s a pretty good chance that Legend and Teigen already know the sex of their second baby. Baby boy or otherwise, it’s an exciting time for Teigen, Legend and not-so-little-anymore Luna.
