On Saturday, both Justin and Hailey Bieber posted photos to celebrate the pop star’s 31st birthday. In Justin’s carousel of pics, he included a new shot of baby Jack, who the couple welcomed in August of 2024. In the image, which Hailey shared in her Stories, the proud parents are talking to Jack as Justin holds him up in the air.

The baby is wearing a bright green onesie, white socks, and a deep blue hat. Hailey wears jeans and a black fleece pullover and Justin is in a gray T-shirt, dark yellow sweatshirt, and charcoal gray track pants.

The model shared a few more photos with her husband in her Stories for his birthday, one in black-and-white in which she is laying in his arms on the floor. Over it, she wrote, “Happy birthday to my love.”

In another picture, she holds Justin while wearing a gray sweatsuit and knitted bucket hat. She’s laughing as he sings into a microphone and several birthday balloons float above them.

Both pics also made it into Justin’s carousel, which included more pictures of Hailey and what looks like a party with his friends. It seems as though a big group accompanied the couple to a cabin somewhere in nature for a weekend of music and fun.

In a second carousel, Justin shared more photos from the event and some from his own childhood sprinkled in, mostly where he is playing with instruments.

Hailey last shared a photo of Jack in November 2024, when she posted about having the “best month of the year.” In her carousel, she started with a photo of an outside walk with Justin, holding Jack strapped to her front.

Justin wore a fluffy camouflage fleece and leaned into his wife to smile for the camera. She was also in a cozy fleece, this one in an animal print, and smiled happily as she hugged Jack.
