Chrissy Teigen Dishes on How She's Preparing Baby Luna for Big Sister Duties

As Chrissy Teigen prepares to welcome another bundle of joy, she’s opening up about her second journey to motherhood and preparing 1-year-old baby Luna for her big sister duties.

"[Luna] is so excited. Actually, she's got her little baby doll now that she's been really taking care of,” the SI Swimsuit beauty gushed while speaking with Entertainment Tonight Wednesday during a rehearsal for Lip Sync Battle LIVE: A Michael Jackson Celebration.

That being said, the social media maven admitted to feeling “nervous” about handling jealousy when welcoming another little one into the Legend household,

"It's hard though, because she's definitely jealous of John [Legend] and I,” the supermodel revealed. “She's so protective of John and when we kiss, she, like, looks [up] from no matter where she is.”

She quipped, ”You see her little dark eyes somewhere. It's a little scary."

The pregnant star — who revealed that she and the “All of Me” crooner are keeping the gender of their second child under wraps for now — continued, “I think the balance is hard. I mean, you want to be able to give one so much attention and shower them with love and affection, but then you have a little baby too, and that'll be rough to balance.”

Sharing her hopes for expanding her brood in the future, Teigen concluded, ”I’m excited to figure it out, because, hopefully, we won't stop at two, and we'll be on our way to Todville.”
