The model previously said that divorce rumors were “made out of thin air”

Hailey Bieber is showing fans that her marriage to Justin Bieber is just fine, thank you very much.

The 27-year-old model further shut down recent divorce rumors by sharing a sweet birthday message to Justin’s mom, Pattie Mallette.

“Happy birthday to my beautiful Mama in law,” she captioned a selfie of the two on Instagram Stories on Wednesday, April 3. “Having another amazing Mom is all anyone could ask for.” In the photo, Bieber and Mallette, 49, pose in front of a lit-up Christmas tree, both wearing simple makeup looks and pink lips.

Amid a flurry of speculation about the state of Hailey and Justin’s marriage, a source told PEOPLE that the couple, who tied the knot in 2018, are “doing really well.”

“There’s no divorce and no truth to that whatsoever,” the insider said on Thursday, April 4. “They are very, very happy.”

In March, Hailey addressed the rumors directly by sharing a message on Instagram Stories.

“Just FYI the stories and constant ‘blind items’ I see on TikTok are 100% of the time wrong Made out of thin air… Come from the land of delusion…” she wrote. “So I know it may be fun feeding into these stories but just know they’re always false xx sorry to spoil it.”

A week earlier, divorce rumors were ignited when Hailey’s father Stephen Baldwin publicly shared a post asking for prayer requests for the couple, who have long been bonded by their faith.

In the post, Justin could be seen playing the guitar and singing “I Could Sing of Your Love Forever” by Delirious? and Hillsong Worship.

“Christians, please when you think of Justin & Hailey, take a moment to offer a little prayer for them to have wisdom, protection and to draw close to the Lord,” the clip’s text read, per Page Six.

Hours after Stephen’s post, Hailey and Justin were spotted attending a late-night church service at the Churchome Church at Saban Theatre in Los Angeles.

Hailey later shared a heartfelt tribute to Justin on Instagram for his 30th birthday.

“30!!!!!!!????!!????!!!!🥹😭 that was fast,” she captioned a March 1 photo carousel featuring various snaps of the couple. “words could never truly describe the beauty of who you are. Happy Birthday to you… love of my life, for life. 🤍.”

The couple also celebrated Easter together, sharing snippets of their festivities on Instagram.

Additionally, Hailey has been hard at work promoting her beauty brand, Rhode. For weeks, the founder has been hinting at a blush launch, and on Tuesday April 2, fans couldn’t help her perfectly flushed cheeks (and matching pink chrome manicure) in a video posted by Rhode.
