The supermodel, 26, and her pop star husband, 29, stepped out in Los Angeles with their adorable pet pooches, who also made an appearance at the spooky party.

Showing off her statuesque figure in a tiny black leather miniskirt, Hailey led the way as she added a matching crop top to the mix.

The stunning beauty also wrapped herself in a tan overcoat for the outing, while a pair of black ballerina flats and designer shades set off the chic look.

Justin pulled up the rear in a casual ensemble of a navy tee, purple cargo shorts and a throwback trucker hat.

The night before, during an appearance at British blogger Vas J. Morgan and Michael Braun’s annual Halloween party, Hailey and Justin stole the spotlight as iconic Flintstones characters.

Rocking a tight PVC outfit, Hailey was Pebbles, complete with a red bobbed wig and a diamond-studded necklace with the letter B.

Justin channeled Bamm-Bamm Rubble by going shirtless, revealing a bunch of tattoos all over his upper body.

The spooky season outing comes after Hailey returned from Paris Fashion Week, where she was promoting her skincare line Rhode.

She kicked off her skincare venture in 2022 and has remained the brand’s creative head from its inception.

Hailey has actively participated in its marketing, including being featured in numerous promotional photos during the past year.

She recently spoke to Forbes about the inspiration behind her new line of products.

‘I think that skincare and beauty should be fun, and these tints are meant to be playful,’ she said.

Meanwhile, Hailey and Justin recently celebrated their fifth wedding anniversary.

After a brief fling in 2015, they rekindled their romance in June 2018.

The couple then became engaged in July 2018 during a picturesque getaway in the Bahamas.

They exchanged vows in a secret courthouse ceremony in September of that year.
