The worst thing about Chrissy Teigen's pregnancy may surprise you

Model Chrissy Teigen reveals the worst part of being pregnant.

Model Chrissy Teigen says the "most annoying thing about pregnancy" is when people compare her baby to fruit.

The 30-year-old model, who announced she was expecting her first child late last year, has admitted she gets so frustrated with people when they liken the size of her and husband John Legend's unborn child to that of a fruit.

Taking to her Twitter account on Saturday, the brunette beauty vowed to be more open about her pregnancy this year and wrote: "The most annoying part of pregnancy is the fruit and veg sh*t. 'Your baby is 6 inches. A pineapple!' What the f**k grocery store we at? (sic)."

She also recently took to Instagram to post a comical pic of herself in a bathing suit, with the caption: "not Vogue Thailand".

Meanwhile, Chrissy and John can't wait for the arrival of their baby following their lengthy struggles to fall pregnant and announced two weeks ago that they're expecting a girl.

But the loved-up duo, who got married in 2013, are still trying to decide on a name for their little daughter.

John, 37, said recently: "We don't have a name yet. We kind of go at it with our own process and think about the names that mean something to us.

"Some of them have family resonance. Some of them are for other sentimental reasons. We'll just decide on our own taste and what means something to us."
