Hailey Bieber's pregnancy hasn't been all peaches. 

One month after announcing she's expecting her first baby with husband Justin Bieber, the Rhode Skin founder shared that she's been facing a physical struggle as a result of her pregnancy—one she wishes she would have been warned about a little sooner.  

Alongside a selfie of her growing baby bump, Hailey joked in a June 12 Instagram Story, "So who was gonna tell me about the lower back pain?"

Of course, the 27-year-old's not alone in her struggle—back discomfort is a common issue among pregnant women that can often be a result of carrying extra weight or changing hormone levels, according to Mayo Clinic. 

Hailey's update isn't the only time she's gotten candid about her road to motherhood. Last week, she provided some insight into the timeline of her pregnancy by revealing just how far along she was while posing for Saint Laurent's Summer 2024 fashion campaign by Anthony Vaccarello. 

Shortly after photos from the shoot were unveiled, the model wrote in a June 3 Instagram Story, "shot this 4 months preggy with little bean in my belly."

But whether she's opening up about her struggles or showing off her baby belly in style, Hailey's in good company. After all, Justin, 30, is also getting ready to become a dad—a responsibility his wife can't wait for him to take on. In fact, Hailey even gave the "Love Yourself" singer's new role a special shoutout after he shared some recents pics of himself. 

"Daily selfies," Justin had captioned the May 30 Instagram post. "Might delete."

Hailey responded in the comments section, "Do not delete!!!!!!" before adding in a separate comment, "Baby daddy."
