Jack Blues Bieber is the ultimate Belieber.

The 13-month-old son of Justin Bieber and Hailey Bieber proved he’s his dad’s biggest fan as he bundled up in an adorable fashion homage to the “Somebody to Love” singer.

In a photo shared on Hailey’s Instagram page Oct. 4, the toddler sat with his back to the camera while wearing a cozy gray hoodie emblazoned with a picture of the “Somebody to Love” singer, taken from his 2010 album My World 2.0.

The sweet nod to Justin’s music history was part of what Hailey, 28, dubbed “Jacktober,” as she showcased pics of the little one modeling various fall looks, including a red and gray striped shirt and solid gray sweatpants. Another image showed Jack getting in the spirit of the season as he observed a skeleton seated atop a bale of hay and surrounded by pumpkins.

Jack also modeled a second look inspired by the Canadian-born singer, who is a noted Toronto Maple Leafs fan. In the fourth slide of the photo carousel, Jack donned a navy sweater bearing the hockey team’s logo, along with a pair of blue jeans and a red beanie hat.
