The "I Don't Care" singer shared several solo pictures of his model babe and sung her praises on Instagram Thursday.
Posting a combination of her model shots and relaxed private life at home, the Grammy winning artist wrote a tear-jerking tribute for Wifey Appreciation Day.
"I fall more in love with you every single day," he wrote.
Bieber added that Hailey is "the greatest thing that has ever happened to me" and spoke from the heart, writing, "I would be lost with out you."
His wife sweetly responded, "best friend."
Mr. and Mrs. Bieber will celebrate their one-year wedding anniversary next month after secretly tying the knot at a New York courthouse in September 2018.
Despite claiming they wanted to have a big celebration, there has been no date set as of yet.
Their first year of marriage has been a turbulent year for Bieber.
As The Blast reported, the 25-year-old sought treatment for depression just months after he wed the model.
Luckily, his new bride stuck by his side and appeared to be very supportive while he was seeking help.
Hailey didn't waste anytime cashing in on her new famous last name.
According to documents, obtained by The Blast, Hailey filed to register "Hailey Bieber" on October 10, 2018 for the purposes of a clothing line.
She also locked up her maiden name, "Hailey Baldwin," as well as a name called "HRB3."
The docs marked the first time Hailey publicaly acknowledged her marriage with JB.
