Chrissy Teigen has joked her daughter Luna may struggle with her baby brother when he's born - because of her own problems with change.

The pregnant model - who already has her 21-month-old girl with her husband John Legend - took to social media this week to share her tongue-in-cheek fears as she gets ready to welcome another child into the world.

She jokingly tweeted: "I'm scared Luna is gonna hate her baby brother because I have a really hard time welcoming new bravo cast members. (sic)"

It comes after Chrissy recently quipped that her unborn son is a "monster", as she found her pregnancy cravings get 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 beauty admitted she's been craving many of the things pregnant women are told to avoid, including cold meats and alcohol.

She said: "I want a cold, Subway deli sandwich at all times. I would love a good margarita, like, a cold margarita."

To curb her cravings, Chrissy has turned to breakfast cereal with cold vanilla coconut milk, and though she's normally behind the home cooking in their household, she's letting her husband "take over".

She recently said: "I'm kind of tired and pregnant and he really takes over.

"The only thing I don't like about him cooking is that it takes me away from him for a long time because he's very slow in the kitchen. Like, painfully slow.

"And sometimes I can hear him from the living room chopping slowly. But it's so cute because he loves to do it."
