Hailey Bieber takes the plunge in low-cut top as she steps out with husband Justin before celebrating son Jack Blues' second birthday

Hailey Bieber and Justin Bieber were recently spotted on a casual outing in Los Angeles.

The couple stepped out together before celebrating their son Jack Blues Bieber's second birthday this week. 

Hailey, 29, showed off her chic sense of style as she paired a light blue, quarter-sleeved top with a low-cut V-neckline that revealed a sliver of her toned midriff. 

She paired the stylish shirt with a pair of navy blue, wide-leg track pants and completed her look with a black, leather shoulder bag. 

She carried a large iced beverage in her hand as she walked toward her and Justin's car during their outing. 

Justin, 32, also opted for a casual look as he rocked a t-shirt, maroon basketball shorts and Ugg boots.

To go with the hues in the rest of his outfit, he wore a black baseball cap with white and red text across the front. 

His wife appeared to be wearing little to no makeup and styled her light brunette tresses in her signature slicked-back bun. 

She wore a pair of massive diamond earrings and shielded her eyes from the summer sun with slim, retro shades featuring a rectangular-shaped frame. 

The pop singer married Hailey in 2018 and they welcomed their first child, son Jack Blues, in 2024. 

After they rang in Jack's birthday on Saturday, August 22, the pair posted a series of adorable new photos to mark the occasion.

The Rhode founder shared several behind-the-scenes snaps of Jack's birthday party on her Instagram Stories. 

She also shared a throwback photo of her posing with her baby bump, writing over the mirror selfie that she took the picture '2 years' ago. 

Some of her other weekend posts included a look at Jack Blues' birthday pancakes topped with candles to start off his morning. 

Earlier this year, Hailey discussed motherhood and 'the most anxiety I have as a parent.' 

In an April interview with Interview Magazine, she said she is worried 'every day' about the world she is raising her toddler in. 

'The world he's growing up in is very, very scary, and it feels so bleak, thinking about the future, with how things are going,' she said at the time. 'But I just have to close my eyes and have faith.' 

She continued: 'As long as he's growing up in an environment at home that's really loving and beautiful, that's all I can hope for.' 

Around the same time, Hailey also answered the question of whether she and Justin plan to have more children after welcoming their son Jack Blues in August 2024. 

'I definitely want more than one, but I'm taking it one at a time,' she said. 'Some days I want two. Some days I want five.' 

She added: 'I always wanted to be married and have kids and a family from a super young age.'
