The 30-year-old model - who will welcome her first child with husband John Legend later this year - admitted she is shocked at how quickly her assets have expanded.

Speaking on US panel show 'FABLife', Chrissy grabbed her left breast and declared: "I'm still in the second trimester and I think, I don't know, I think I'm rocking a 440DD! I have no idea how."

Holding up a tiny bra, she laughed and added: "It's like a nipple cover for me."

Chrissy and John are delighted to be welcoming their baby following their lengthy struggles to conceive and announced two weeks ago that they're expecting a girl.

But the model - who married John, 37, in 2013 - revealed the "most annoying thing about pregnancy" is when people compare her baby to fruit.

Taking to her Twitter account to express her frustration after one such occasion, she 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)."
