The 31-year-old Grammy winner gave fans another peek into fatherhood on Monday, September 8, when he posted new Instagram photos of himself and his son, Jack Blues, enjoying a day on the water.

In the snapshots, the father-son duo sit together in a kayak, both gazing out across the lake with their backs to the camera. Little Jack sits securely on his dad’s lap, while Justin sports a cozy red sweatshirt, matching sweatpants, and a beanie.

While Justin and his wife Hailey Bieber are known for keeping their child’s face largely private, the couple occasionally shares sweet glimpses of their life with Jack.

Alongside the kayak photos, the singer also uploaded a few casual selfies in the same red beanie, captioning the post simply with a cherry emoji: “🍒.”

The family outing came just a week after Jack’s first birthday celebrations. On August 28, Hailey, 28, shared photos from the festive day, which featured a summer poolside party with friends, including Kendall Jenner.

The party was playfully themed “Camp Jack,” complete with photo booth snaps of Hailey cuddling her son. “Camp counselor ⛺️,” she joked in her caption.

Hailey also marked the milestone with a heartfelt Instagram tribute, posting a carousel of moments with Jack. In one image, she beams as she lifts him in the air, while another shows her kissing his forehead.

“1 year of you my beautiful boy. Happy 1st Birthday Jack Blues, you are joy personified🩵,” she wrote.

Justin, who has been open about embracing fatherhood, also shared his own birthday post for Jack back on August 18. His carousel of images showed tender moments, including Jack perched happily on his dad’s shoulders and Justin holding his little one close.

The singer, known for global hits like Peaches and Love Yourself, has leaned into his quieter family life in recent years, with Hailey and Jack at the center of it.

For fans, the rare photos are a reminder that even one of the world’s biggest pop stars treasures the simple joys of fatherhood — a kayak ride, a birthday party, and the chance to watch his son grow.
