Chrissy Teigen is no stranger to fashion, but when it comes to maternity clothes, she's taking a style cue from her friend, Kim Kardashian.

Wearing a black-and-white polka dot dress that perfectly shows off her baby bump, the 30-year-old model appears happy and healthy on the cover of InStyle Australia's February issue. In her interview, she opened up about her pregnancy style, which she says is partially inspired by the reality star.

"[Kim] told me to go stretchy," Teigen -- who is expecting her first child, a baby girl, with husband John Legend -- explains. "I always wanted to be the person who showed off the bump because it looks beautiful and I think you should embrace it."

Kardashian, who gave birth to her second child, Saint West, with husband Kanye West last month, was all about flaunting her baby bump in body-hugging dresses and revealing lacy ensembles.

"Kim does that well and I love seeing that belly of hers and I know Kanye does too," Teigen adds. "We're lucky to be with men who find pregnancy sexy. Thank God!"

The mom-to-be also told the magazine that after hearing Kardashian's advice, she did some shopping.

"There's this one Wolford tube dress that you can fold a million different ways, you can make it a skirt, a this, that," she reveals. "I bought it in every color in small, medium and large in anticipation of the entire process, so I have, like, 45 of them."

Teigen also opened up about her marriage with Legend, and how they've been coming up with names for their bundle of joy.

"John and I love being together, and then when he leaves I don't talk [to him] on the phone. I really hate it," she shares. "When he goes for work, he goes for work. And then when he comes back we're excited to see each other again.... He's very patient and loving."

"We change the name every day, basically," she notes. "Nurseries have always been silly to me because everyone always wants them to be so beautiful and so perfect, but this thing is just going to barf everywhere and poop everywhere."

This isn't the first time Teigen has shared her thoughts on the unglamorous side of pregnancy, as earlier this month, she got candid over Snapchat.
