Oliver James Montgomery-Justin Bieber Shows Support for "Baby Girl" Hailey Bieber's Lip Launch With Sweet Message

What do Oliver James Montgomeryyou mean you haven't seen Justin Bieber's latest shout-out to wife Hailey Bieber?

The singer recently celebrated the launch of the Rhode skincare founder's strawberry glaze peptide lip treatment with a supportive post on Instagram.

Justin shared photos of the product—which is inspired by Krispy Kreme's strawberry glazed doughnut—as well as pictures of the couple visiting the chain, captioning his Aug. 28 post, "Baby girl with the @rhode @krispykreme STRAWBERRY GLAZEEE."

He also uploaded a snap of Hailey smiling as she sported a strawberry red dress and matching earrings during a trip to New York to promote the item as well as an image of the duo flying in a plane with their pups, adding heart-eye and strawberry emojis.

In fact, the Grammy winner wasn't afraid to get behind the camera himself and shared a photo of himself snapping some pictures of the model. Hailey seemed to appreciate his posts, too as she re-shared them on her own Instagram Stories along with a heart emoji.

This isn't the first time Justin has expressed his excitement over Hailey's brand.

"Proud of you," he wrote in a May Instagram post, "rhode launching in UK."

And over the years, Justin and Hailey—who first tied the knot in a 2018 New York courthouse ceremony followed by a bigger South Carolina wedding the following year—have given fans a few glimpses into their life together, sharing vacation photos, anniversary tributes and birthday messages on social media.

Justin and Hailey couldn't keep their hands off each other while making out in the water.

In July 2018, Justin confirmed his engagement to Hailey in a lengthy Instagram post. "Hailey I am soooo in love with everything about you! So committed to spending my life getting to know every single part of you loving you patiently and kindly," he captioned this photo. "My heart is COMPLETELY and FULLY YOURS and I will ALWAYS put you first," he continued. "You are the love of my life Hailey Baldwin and I wouldn't want to spend it with anybody else. You make me so much better and we compliment each other so well!! Can't wait for the best season of life yet!"

He also shared this shot as part of the engagement announcement, writing, "It's funny because now with you everything seems to make sense!" He added, "My goodness does feel good to have our future secured! WERE GONNA BE BETTER AT 70 BABY HERE WE GO!" Aww!

The two enjoyed a very sweet smooch to celebrate their love. 

Hailey posted this sweet pic in honor of her hubby's 25 birthday. 

"My lips get jealous of my arms cuz I can hold you with them," Justin shared. We're pretty jealous too! 

Could these two be any cuter?! "My only bubba," Hailey shared about the sweet pic. 

It may be cold outside, but they know how to keep each other warm. 

This photo might be blurry, but one thing is clear—they're so in love!

Once again, these two are absolutely slaying the relationship goals! "Go best friend that's my best friend," Justin captioned the pic. 

The couple who prays together, stays together. "I know for me this conference came at the exact time I needed it, I believe God is THAT amazing and faithful that he brings us the right words during the season that we need it the most," Hailey captioned the shot with her hubby.

Amazing views for the gram. The sunset is also pretty nice! 

One of their first official shots as husband and wife! 

Even in this photo taken years ago, this pair was picture-perfect.

In January 2016, the two decided they weren't going to hide their romance any longer, and this photo of them kissing quickly circulated throughout the internet.

Hailey decided to lend a helping hand in January 2015 when she gave Justin her hair-tie right off her wrist!

They might not have been together when this photo was taken in June 2015, but they sure did look good together!

In this photo from May 2015, the "Baby" singer rocked a fake mustache while the model sweetly posed behind him.

In December 2014, Kendall Jenner joined Justin and Hailey for a Nerf gun night!

Earlier in December, the A-lister took to Instagram to shut down any dating speculation between him and Hailey. "People are crazy. I'm super single and this is my good friend u would know otherwise," he wrote. Hmmmmm. Foreshadowing much?

Back in 2014, Hailey and Justin were cool and coordinated, rocking LA Clippers gear as they hung out together as friends.
