Hailey Bieber attended a promotional event for her skincare line Rhode in New York City on Sunday, wearing two distinct outfits.

The 27-year-old expectant mom, accompanied by a casually dressed Justin Bieber, wore a tan-hued maxi dress and matching boxy blazer.

The low-cut style revealed the model’s busty cleavage, as the clinging number gathered beneath her growing bump.

Meanwhile, the 30-year-old Canadian crooner contrasted with his wife by wearing a blue puffer vest, baggy shorts, white socks, and black Drew House slippers.

Justin wore a blue and green Angels baseball cap and showed off his highly inked arms as he skipped a shirt.

The fashionista paired her blazer with corresponding pointy-toe heels and stylish, narrow brown-framed sunglasses.

She accessorized with a little camel-colored leather purse and round gold coin-shaped earrings.

Bieber’s beautiful brown hair was styled in a deep, precise center part and slicked back into a chignon.

Her face was glowing with dewy makeup, which featured a flush of soft pink blush and a moisturizing mauve hue on her lips.

Lovebirds Hailey and Justin, who married in 2018, are expecting their first child.

They drove fans and friends into a frenzy when they shared their 𝚋𝚊𝚋𝚢 news on social media in May.

They shared footage from their vow renewal in Hawaii, revealing Hailey’s 𝚋𝚊𝚋𝚢 bulge.

Last fall Hailey acknowledged that she and her husband often wear mismatched styles, telling GQ Hype : ‘It’s so funny because I see so many people talk about this’

‘He may want to wear baggy sweats to dinner, and I might want to wear a tiny little dress just because that’s how I’m feeling,’ the runway regular said last year about her and Justin’s different styles

Hailey exposed her long toned leg as she and her hubby entered a black sprinter automobile.

Since then, the attractive entrepreneur has publicly shown her growing tummy in fashion-forward maternity outfits.

In late May, the beauty convinced her social media followers that she had hinted at the 𝓈ℯ𝓍 of her unborn child by writing in a caption, ‘small cherry blossoms on my nails, little cherry blossom in my tummy.’

Fans interpreted the remark to suggest that she and the pop singer are expecting a girl, despite neither has publicly commented on the matter.

Last October, Hailey explained why she and her husband frequently wore mismatched outfits.

She told GQ Hype: ‘It’s so funny because I see so many people talk about this.’

The beauty also noted that her husband usually gets dressed before she does.

‘He may want to wear baggy sweats to dinner, and I might want to wear a tiny little dress just because that’s how I’m feeling.

‘We can’t sit there and be like, “So I’m going to wear this and you’re going to wear this,”‘ she emphasized.

Bieber’s beautiful brown hair was done in a deep, precise center part and slicked back into a chignon.

Hailey has been prospering professionally while also preparing for motherhood.

Last week, the star celebrated two years of her Rhode skincare line and unveiled new products.

“2 years of @rhode,” she began an Instagram caption, adding, ‘Feel so very fortunate that I get to bring this world of rhode to life everyday with the most fantastic team of extraordinary, creative people.’

The statement to her 52.5 million fans read: ‘So thankful beyond words for the support and love provided… We’re just getting started. HBD Rhode.’
