Hailey Baldwin is showing off her sexy abs now, but if hubby Justin Bieber has his way, he'll be putting a baby in that belly sometime soon!

Hails went out for some coffee in tight vintage jeans, shearling slides, and an off-the-shoulder orange cropped cardigan and when she lifted her arm to adjust her sexy-librarian glasses, BAM! -- we got a peek at her amazing abs.

The sexy supermodel might not have that slim, trim stomach for long, though -- seems like she and Justin and looking to start a family soon and we bet she'll be pregnant before the end of the year! Wouldn't that be CRAZY?! A little Bieber baby?!

Justin posted on Instagram today about his recent struggles. He explained why he won't tour any time soon, though he WILL come out with some new music -- but he admits he wants to get himself mentally in order before becoming a dad. A DAD! Bieber babies on the brain!!! Here's what he wrote: "So I read a lot of messages saying you want an album .. I’ve toured my whole teenage life, and early 20s, I realized and as you guys probably saw I was unhappy last tour and I don’t deserve that and you don’t deserve that, you pay money to come and have a lively energetic fun light concert and I was unable emotionally to give you that near the end of the tour. I have been looking, seeking, trial and error as most of us do, I am now very focused on repairing some of the deep rooted issues that I have as most of us have, so that I don’t fall apart, so that I can sustain my marriage and be the father I want to be. Music is very important to me but Nothing comes before my family and my health. I will come with a kick ass album ASAP, my swag is undeniable and my drive is indescribable his love is supernatural his grace is that reliable.... the top is where I reside period whether I make music or not the king said so. 👑 but I will come with a vengeance believe that.. (grammar and punctuation will be terrible pretend it’s a text where u just don’t care)."

We love his honesty, his humility, and his work to get healthy. Mental and emotional health isn't a give -- we have to work at it, and Justin seems to know this. Between his faith and his clean living and his love for Hailey, we're pretty sure he's gonna come out on top!
