New mom Hailey, 28, celebrated the start of the new year by donning a pink bikini, cheetah-print fur coat and ugg boots. In a nod to the holiday season, the model also wore a Happy New Year headband. Jewelry-wise, Hailey opted for a large jewel-encrusted “B” pendant and another with the initials “JBB,” for son Jack Blues, whom she shares with the “Baby” singer.

And one person who was a big fan of her sexy style was her husband of six years. “Um. Goin anywhere with u bb,” Justin, 30, captioned an Instagram Stories post of Hailey posing in her outfit and saluting. “Happy new year,” he added to the caption.

On Wednesday, Jan. 1, the Rhode Beauty founder offered further insight into their celebrations — which featured martinis and caviar-topped In-N-Out burgers — with a carousel grid post on Instagram. “Wake up, it’s 2025!” the star captioned her post.

Just days before the celebrations, Hailey shared a black-and-white pregnancy throwback picture thanking 2024 alongside a baby angel emoji, presumably a reference to Jack Blues, whose birth was announced on Aug. 23.

The snapshot, which was shared on Dec. 30, shows Hailey looking off-camera as she holds up her shirt, revealing her bare baby bump.

On Aug. 23, Justin announced on his Instagram that the couple had welcomed their first child. “WELCOME HOME JACK BLUES BIEBER,” he wrote in the post. Soon afterward, Hailey posted the same photo to her Instagram Stories with the child’s name, a teddy bear and a blue heart emoji.

Jack Blues’ name continues a family tradition for the Biebers, as the baby shares his initials with his dad, his grandfather, Jeremy Bieber, and some of Justin’s siblings.

While the pair have kept the little one largely out of the spotlight they did share an image of a family walk with Jack back in November, reflecting that it was the “best month of the year.”

The wholesome family moment saw the duo wrapped up in hoodies and fur coats while Jack — who was also sporting a hoodie — was worn by Hailey in a baby carrier.

Other snaps in the carousel post featured a few other personal and professional highlights from Hailey’s November — including images of some new Rhode products, a handful of selfies and a shot of some cinnamon rolls.
