Hailey Bieber shows off lean postpartum figure on a rare night away from baby Jack Blues in Los Angeles

New mom Hailey Bieber showed off her incredibly lean postpartum figure on a rare night away from her son, Jack Blues, on a dinner date with pal Lori Harvey

Less than a month after giving birth to her first child, who she shares with husband Justin Bieber, the supermodel, 27, had that unmistakable new mom glow as she left a sushi restaurant in Los Angeles on Wednesday night. 

For her laid-back outing, the Rhode founder sported an oversized leather jacket and black tank top, which she kept tucked into her faded blue jeans, and dark nail polish. 

She kept her accessories to a minimum, apart from a pair of rectangular sunglasses and her recently upgraded engagement ring, estimated to cost $1.5 million dollars.

Since welcoming her baby boy last month, the Vogue cover girl has only been seen out two other times.

Her first public outings included meeting up with her longtime friend, Kylie Jenner, for dinner and a solo trip to the spa

Last week, the mother-of-one rang in her sixth wedding anniversary with Justin. 

On Friday evening, she gave her 53.3 million Instagram followers a glimpse of how they marked the special occasion by sharing photos of candles, twinkly lights and balloons. 

Despite taking a step back from posting personal pictures on her Instagram since becoming a mom, the Rhode founder couldn't resist sharing a few moments from her anniversary, which seemingly began with Justin surprising her with balloons.

After uploading a snap to her Instagram Story of two gold balloons covered with red hearts, she shared a video of some flickering candles.

Her third and final post featured her holding a polaroid picture of them kissing.

'6 years,' she wrote on the image. 'Love you baby.'

The couple tied the knot at a New York City courthouse on September 13, 2018 just months after Justin's finite split from his on/off girlfriend Selena Gomez.

After saying their 'I Dos' at an NYC courthouse, Justin and Hailey hosted an elaborate ceremony the following year at Montage Palmetto Bluff hotel in South Carolina.

They were first introduced in 2009 at TODAY when Hailey's father, Stephen Baldwin, introduced them to each other.

The pair then had a brief fling in 2016 amid his on/off decade-long romance with Selena Gomez.

When he and the Disney Channel alum, 30, finally called it quits for good in May 2018, Justin fell into Hailey's arms and they've been attached at the hip since.

The pair have spoken candidly about their relationship over the years — including their 'really tough' first year of marriage.

Speaking to GQ in 2021, Justin revealed that his and Hailey's initial difficulties stemmed from 'trauma' and 'just lack of trust.'

'There was all these things that you don't want to admit to the person that you're with, because it's scary. You don't want to scare them off by saying, 'I'm scared,'' he explained.

The Sorry hitmaker admitted during the first year of marriage he was 'on eggshells' but now he's never felt more stable.

Hailey and Justin welcomed their first child at the end of August and shared the sweet name they had chosen.

Justin shared a photo of their new son's adorably tiny foot, while revealing that they had named him 'Jack Blues Bieber.'

'WELCOME HOME,' the singer wrote to Jack in the caption. Notably, the couple didn't clarify when their son was born.

Hailey reposted the photo to her Instagram Stories shortly after Justin's initial post.

She captioned it with a teddy bear emoji and a blue heart, writing, 'Jack Blues.'

The name 'Jack' appears to have personal significance for the lovebirds, as it is the middle name of Justin father Jeremy Bieber.

Jeremy split from Justin's mother Pattie shortly after his birth in Ontario, Canada, when both were just 18.

The hitmaker initially saw little of his father as a child, but the two reconnected and have spent significantly more time together since Justin became an adult, solidifying their father–son relationship.

 Jack was delivered by Dr. Thais Aliabadi, the same OBGYN that Kylie and sister Khloé Kardashian used to deliver their children, according to the birth certificate obtained by TMZ.

Baby Bieber was born at Cedars-Sinai Medical Center in Los Angeles, where Kylie's daughter Stormi Webster was born in 2018.

Hailey and Justin were prepared for Jack's birth, as a source told People in July that the two were 'ready to become parents.'

'They're planning for the baby's arrival and it's very cute,' they said.

The 'very religious' couple were said to have leaned on their Christian faith and their church community for support as Jack's birth approached.

The insider added that Hailey was 'fiercely protective of her and Justin's growing tribe,' following reports that she was not currently 'close' with her family.
