Surpassing:Hailey Bieber shows off baby bump in W Magazine cover, opens up about relationship

Sun's out,Surpassing bumps out.

Hailey Bieber's baby bump made the cover of W Magazine’s Summer Issue. The model and entrepreneur shared her concerns about being a mom, why she decided to wait to share the news at six months pregnant and what it's like dealing with constant scrutiny over her relationship with husband Justin Bieber.

In photos shared by the publication Tuesday, the model posed in various states to show off her pregnancy belly, including the cover in which she wore a black bra and black tights while seated in a chair.

She also embraced maternity fashion in an oversized chunky knit sweater and tights for one photo, a figure-hugging mesh dress in another and a photo of her stretching in an unbuttoned button-down and black underwear.

Hailey Bieber announced the upcoming arrival of her little one on Instagram on May 9. Her rep confirmed the news to USA TODAY and added that "she's a little over six months" pregnant.

Addressing the delay in her announcement, she told W Magazine, "I didn’t have a belly, really, until I was six months pregnant, which was when I announced it. I was able to wear big jackets and stuff."

"I probably could have hid it until the end, but I didn’t enjoy the stress of not being able to enjoy my pregnancy outwardly. I felt like I was hiding this big secret, and it didn’t feel good. I wanted the freedom to go out and live my life," the Rhode founder added.

Hailey Bieber admitted that although she's being open about her pregnancy and sharing it with fans, she's aware it may come with vitriol.

"People have made me feel so bad about my relationship since day one. 'Oh, they’re falling apart. They hate each other. They’re getting divorced.' It’s like people don’t want to believe that we’re happy," she said. "I used to try to act like it hurts less and less. I’ve tried to think that you get used to it at a certain point, that this is what’s going to be said and this is how people are going to be. But I realize that it doesn’t actually ever hurt any less."

Though she and the "Peaches" singer are happy, Hailey Bieber revealed pregnancy brought up some intense emotions about their relationship.

"In the beginning (of pregnancy), it was super emotional for me. Like, ‘I love this human so much. How can I possibly bring someone else into this?'" she said, referring to her husband. "I’m trying to soak in these days of it being Justin and me, just the two of us."

The entrepreneur added that she planned to spend some solo time out at the couple's home in Idaho. "He’s already there waiting for me," she shared at the conclusion of her interview.

Hailey Bieber, the daughter of youngest Baldwin brother Stephen Baldwin, told GQ in October that she first met Justin Bieber, then 15, when she was 12, during a 2009 appearance on the "Today" show.

Much later, the pair became romantically linked and then tied the knot in September 2018.
