From the jump, there was no mystery as to the gender of the baby.
"I've made this decision," she told People magazine. "Not only am I having a girl, but I picked the girl from her little embryo. I picked her and was like, 'Let's put in the girl.'"
However, not long after Chrissy's decision to choose a girl were made public, many took to social media to blast her, implying that she's handpicking qualities that she wants, rather than letting nature take its course.
The often-outspoken model, though, was quick to defend herself to the twitter-haters.
"My natural blessing from god was infertility," she tweeted.
In a separate tweet, she said, "What year is this!? And for the record, I am always happy and open to speak on infertility. The more casual, the better! I don't mind."
As the criticism continued pouring in, she said, "I also picked the embryo with a taste for bacon, a knack for magic and size 7 feet so she can always find shoes."
Haters or not, Chrissy isn't going to let anyone steal her baby bliss.
"I think I was most excited and allured by the fact that John would be the best father to a little girl. That excited me," she told the magazine. "It excited me to see … just the thought of seeing him with a little girl. I think he deserves a little girl. I think he deserves that bond."
Chrissy said she wants John to have a little partner-in-crime eventually, too.
"A boy will come along. We'll get there too, so it's not like we really have to pick," she said. "But he definitely is very lucky to have a little girl. And this girl is going to be so completely lucky to have John as her papa — it's crazy!"
John, she said, will be wrapped around their daughter's finger.
The beauty and "Lip Sync Battle" star has been busy promoting her book Cravings, but she knows that her priorities are about to shift, as will John's.
"I'm excited to see what he is going to do because I think we'll have two very different styles. I'm excited to see that part of John," she told the magazine. "We've been together so long, and sometimes we look at each other and we're like, 'I know everything about you and you know everything about me,' but we have no idea what we're going to be like as parents. I think it'll be really fun. I'm excited."
For now, they're getting parenting practice on their dog, Putty, as weird as that sounds.
"Putty our bulldog was John's first dog ever," she says. "He never suspected he could love something like that ever, so it's so funny seeing him interact with them and knowing that's the way he's going to speak to our kid."
So, what does John Legend baby talk sound like? "John's very big on full sentences and not doing baby talk," Chrissy said. "Even when he's talking to the dog he's like, 'Putty, you need to go outside and use the restroom today.' And I'm like, 'What the f------, it's a dog! You're crazy!'"
