Chrissy Teigen is just a few weeks away from giving birth to her first child with husband John Legend, but that hasn't stopped the star from changing up her looks. The 30-year-old gave fans a glimpse of her new look on Instagram, having chopped her long wavy tresses into a chic bob.

Chrissy Teigen revealed she has cut her hair into a shoulder-length bob

The model confessed that she had a very specific idea of what she wanted her new hairstyle to look like, so she turned to none other than Jen Atkin – the woman behind the Kardashian-Jenner clan's sleek manes – to help her achieve the style she was after.

"New cut!!" Chrissy wrote to her 5.6 million followers, alongside a short video of herself pouting and showing off her makeover. "Asked for the khloe-rosie, side of Chrissy khlosey and @jenatkinhair knew exactly what I meant".

It could be that "khloe-rosie" is referring to Khloé Kardashian and Rosie Huntington-Whiteley, both of whom also sport tousled shoulder-length styles, similar to Chrissy's new look.

The clip also gave fans a glimpse of Chrissy's blossoming baby bump, with the American beauty showing off her pregnancy figure in a black crop top and matching leggings.

As Chrissy and John prepare to welcome the new arrival, whom they have revealed will be a little girl, the couple celebrated last week with a princess-themed baby shower held at Material Good, a space in New York designed to look like a chic city apartment.

Having spoken openly about their decision to turn to IVF, Chrissy recently defended herself on Twitter after she faced criticism when she admitted she chose a female embryo during the treatment.

"From reading everything tonight, I think I made a mistake in thinking people understood the process better than they do, which is my fault," she wrote. "We didn't create a little girl. We had multiple embryos. Girls and boys. We simply chose to put in a female first (and second)... We didn't 'throw away' anything and still would love to have more of both in the future.

"Hard to explain such a complicated process here… You'd be surprised at how many people you know go through this. Also every doctor knows the sex of the embryos, it isn't some grand secret..."
