Chrissy Teigen shut down another Twitter troll on Monday, who criticised the model for using IVF to conceive.

Over the weekend Chrissy, who has been open about her experiences with IVF, told Extra that she and husband John Legend plan on having a son next, saying they have “have a boy on ice.”

“We have a boy on ice.” Chrissy told Extra. When asked when the couple would consider having a second baby , the model added: “when we get to stay at home. John goes on tour, I think, all of May, so after that, I guess.” She then joked: ”He’s literally like, ‘Please unfreeze me.’”

On Twitter, Monday Chrissy further confirmed her baby plans, sharing: “Since this is coming up again, I said our next baby would be a boy because that is the embryo we have left. A boy. So. Yeah. And no, I am not pregnant.”

But Chrissy’s tweet led one user to respond: “did you give it a minute to try naturally or are you avoiding ‘the act?’ At least no political rants!” To which the model clapped back: “Hi Linda, thanks for asking, you complete witch. I tried for about 9 years. Anything else, let me know!”

Chrissy and John welcomed daughter Luna last April and before the baby’s arrival the ‘Lip Sync Battle’ host revealed the couple had chosen to have a girl. Speaking to People last February, Chrissy shared: “I’ve made this decision.

“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.’” Chrissy later came under a barrage criticism on Twitter for selecting the baby’s gender.

Responding to the critics, Chrissy later tweeted: “This is all so interesting. I said it so casually because i'm just open. I'm around so many open-minded people & forgot it's controversial. Anyhow I am not mad at anyone's beliefs but I don't really actively seek out people to make them feel bad about their decisions either.”
