Luna's going to be a big sister! Chrissy Teigen and John Legend are expecting their second child, People reports.

Chrissy made the big, joyful announcement on Instagram today, Tuesday, November 21, by taking to Instagram to share a clip featuring 19-month-old Luna. In the video, Chrissy asks her LO, "Luna, what's in here?" while pointing to her stomach. Luna's OMG-adorable reply? "Baby." Chrissy cheekily captioned the post "it's John's!" John then jokingly commented on the post, "Maury will have the final word on this." Ha!

The celeb parents have been very vocal about trying for a sibling for Luna over the past year. Teigen opened up about her fertility struggles to InStyle for their November issue. After conceiving Luna via IVF, the celeb power couple had one final frozen embryo that Chrissy was planning on having implanted sometime this year. And back in January, Teigen revealed that the last embryo is male, so it's likely that this LO is a boy!

The couple's hinting at a second pregnancy reached a fever pitch in recent weeks. Chrissy addressed the topic with E! News on Thursday, November 2: "We're still trying... I'm going for, I mean hopefully in the next few years, because for me I really want to just knock 'em out," Chrissy said, adding that she's feeling "good."

She then elaborated that she's looking forward to being pregnant again. "That's my dream, I want to just be pregnant kind of for the rest of my life," she confessed. "Not for the rest of my life, but the rest of my fertile life. So we'll see."

And on Friday, November 17, John told People that he and Chrissy were "working on" baby number two and that "hopefully it will be soon." In retrospect, we can see that by "it," it seems he meant their official announcement.

Huge congrats to the growing Stephens family!
