"She is so excited. Actually, she's got her little baby doll now that she's been really taking care of," gushed Teigen.
"It's hard though, because she's definitely jealous of John and I," she added, before explaining that their daughter is "protective" of her dad. "She's so protective of John, and when we kiss, she like, looks [up] from no matter where she is."
Meanwhile, Legend couldn't help but share why he's most excited to have a "little Johnny" in the house.
“It’s always exciting, because you never know what they're going to be like,” Legend told ET in April. “You’re just excited that another product of your relationship and your love is going to be out there in front of you.”
“We're just excited to see how we're going to be as parents of two, and how Luna is going to be as a big sister,” he added. “It’s going to be really exciting and fun.”
