Chrissy Teigen is "scared" her daughter won't like her baby brother.
The 32-year-old model is due to give to her second child in around three months' time, but has admitted she's concerned that her 21-month-old daughter Luna, whom she has with her husband John Legend, will struggle to adapt to her new sibling when he arrives.
Taking to her Twitter account, Chrissy quipped: "I'm scared Luna is gonna hate her baby brother because I have a really hard time welcoming new bravo cast members."
The brunette beauty has been glowing throughout her pregnancy but has admitted her unborn son must be a "monster" because her food cravings are out of control.
She joked on Twitter: "This baby is sucking the life from me. Drinking my water, making me dry. Eating my food, making me hungry. Taking my health, making me sick. Why do we create these monsters they want us dead? (sic)"
Meanwhile, the American beauty previously admitted to suffering postpartum depression following the arrival of her daughter.
And Chrissy confessed that, at one stage, she struggled to see a time when she'd feel like herself once again.
Asked what advice she's give to other women who are going through a similar experience, Chrissy said: "Just know that there's a light on the other side.
"When I was in the midst of everything, I could never imagine myself on the other side of it. Now, I'm able to look at September, October, November, December, and shake my head at how dark and crazy of a period it was.
"Unfortunately, you can only really do that when you're out of it. There's no other way to explain it. And there's no better feeling than being out of it."
