Hailey Bieber left little to the imagination as she attended Vas J Morgan’s Halloween party with husband Justin in West Hollywood on Saturday.

The supermodel, 25, looked nothing short of sensational as she copied a runway look by Laetitia Casta for YSL spring/summer 1999 for her costume for the annual holiday.

Hailey wowed in the pretty pink flowers which kept her modesty as she wrapped the sheer purple long train around her as she arrived.

Making sure all eyes were on her, the beauty added inches to her frame in towering heels with coordinated flowers on and rocked a khaki handbag.

Hailey styled her long tresses in luxurious waves as she added the large flowered head piece to complete the look.

She took to Instagram to tease the glamorous racy outfit to her 48.9 million followers as she flashed her toned figure to the camera for mirror selfies.

Justin and Hailey began dating in late-2015, but broke up not long after. They reconciled in June 2018 just three months after breaking up with longtime girlfriend Selena Gomez.

The couple became engaged the following month and married that same year in a lavish star studded ceremony.

Justin and Hailey have been able to spend quite a bit of time together in recent weeks because the pop superstar put his Justice World Tour on pause.

The tour was originally set to begin in Seattle, Washington on May 14, 2020 and go through and conclude on September 26, 2020.

But, like all musical artists around the world, it had to be scrapped due to COVID-19, which was eventually deemed a pandemic in mid-March of that year.

First the tour was pushed back to the following year, and then again to 2022.

Eventually it kicked off on February 18, 2022 with a show at Pechanga Arena in San Diego, with an end date set for March 25, 2023.

However, more problems would arise, resulting in a number of postponed and cancelled shows, culminating with the plug being pulled altogether on the Justice World Tour after a show in Rio de Janeiro on September 4, due to Bieber wanting to prioritize his health.

Following the performance at Rock in Rio in Brazil, Bieber confessed, ‘the exhaustion overtook me and I realized that I need to make my health the priority right now,’ he said in a statement as reported by ABC, adding, ‘So I’m going to take a break from touring for the time being. ‘I’m going to be ok, but I need time to rest and get better.’

Bieber’s on-again, off-again tour comes in the wake of his doctors diagnosing him with Ramsay Hunt syndrome, which the Mayo Clinic says ‘occurs when a shingles outbreak affects the facial nerve near one of your ears.

In addition to the painful shingles rash, Ramsay Hunt syndrome can cause facial paralysis and hearing loss in the affected ear.’
