Hailey Bieber is honoring her baby boy with her bling.
The model gave multiple looks at her new sparkly necklace featuring Jack Blues’ initials in an Instagram slideshow Tuesday.
“It’s October and I’m someone’s Mom 🎃,” the 27-year-old captioned the carousel.
The Rhode beauty founder upload included one close-up snap of the Alex Moss design, as well as another glimpse in a face mask mirror selfie.
The necklace features nearly 4 carats of pavé-set natural white diamonds, set in 14K gold, the jeweler tells Page Six Style in a press release. She paired the pendant with massive “B” necklace, also by Moss, she got as an homage to her new last name when the couple were married in 2019.
She concluded the slideshow by debuting husband Justin Bieber’s baseball cap, also dedicated to their 1-month-old baby.
The back of the 30-year-old “Baby” singer’s hat was stitched with the little one’s first and middle name in blue.
Hailey gave birth to their infant in August, with Justin sharing a sweet shot of the newborn’s foot with his Instagram followers at the time, writing, “WELCOME HOME.”
Shortly after, the model showed off her new manicure — and a diamond “Mom” ring she had acquired, of course.
Three months prior, the couple revealed they were starting a family while sharing photos from their vow renewal in Hawaii.
Hailey debuted her baby bump in a lace Saint Laurent dress in the May pictures.
She spoke to W magazine in July about keeping the news under wraps for six months since she “stayed small for a long time.”
The then-expectant star explained, “I didn’t have a belly, really. … I was able to wear big jackets and stuff.”
Keeping her secret, however, brought Hailey “stress” as she desired the “freedom to go out and live [her] life.”
The makeup mogul and Justin have been married since September 2018 when they wed in a New York City courthouse.
The duo tied the knot again in front of their loved ones in South Carolina the following year.
