Hailey Bieber supports pal Camila Morrone at TV show premiere after Justin's 'heated exchange' with ex-mentor Usher at Oscars bash

Hailey Bieber made a solo, public appearance on Thursday to support her gal pal Camila Morrone at the premiere of Something Very Bad Is Going To Happen.

The 29-year-old model was spotted making a low-key entrance at the event held in Hollywood and opted out of walking the red carpet.

The Rhode founder wore an all-black ensemble featuring a silk, button-down blouse and a tight-fitting miniskirt 

Bieber's hair was slicked back into her signature bun and her eyes shielded by skinny, oval-shaped sunglasses.

She carried a clutch and accessorized with gold jewelry as she greeted Morrone, 28, and her co-stars in the new Netflix horror miniseries produced by the Duffer Brothers. 

The mother-of-one appeared to be watching her friend Morrone from the sidelines as she did her glamorous walk down the red carpet outside The Egyptian Theater.

At one point, Bieber was seen craning her neck and smiling as she seemingly tried to catch Morrone's eye.

For the premiere, Morrone was dripping in red carpet glamour as she modeled a revealing black lingerie look.

The ex-girlfriend of Leonardo DiCaprio showcased her enviable figure in a see-through, lace crop top and a matching maxi skirt. 

On the red carpet, Morrone flashed a warm smile as she posed for photos with costar Adam DiMarco. 

Morrone, who previously dated DiCaprio for five years and is currently dating music video director Cole Bennett, also shared a fun red carpet moment with DiMarco as they held up their hands to each other.

DiMarco, 35, looked dapper in an all-black outfit to coordinate with Morrone's sexy outfit.

In the eight-part horror series, Morrone and DiMarco play a couple to be wed.

The story follows the pair as they encounter and experience a set of eerie and spooky coincidences ahead of their wedding ceremony. 

Later, the duo were seen posing with the rest of the cast of their new show, including Jennifer Jason Leigh, Jeff Wilbusch, Gus Birney, Ted Levine and Sawyer Fraser. 

For her red carpet look, Leigh served elegant glamour in a beige, tweed set featuring a short-sleeved blazer and a matching midi skirt. 

The TV icon, 64, paired the chic outfit with a Hermès clutch and black, slingback pumps. 

Their fellow castmate Jeff Wilbusch was also at the premiere in a particularly sharp look. 

He paired a light gray blazer and matching trousers with a dark blue button-down.

Selling Sunset star Alex Hall also attended the premiere in a deep purple minidress with a halter neckline. 

She paired the silk garment with beige heels and a topknot as she posed on the red carpet. 

Station 19 actor Carlos Miranda also joined in on the star parade for the premiere in business casual attire. 

The Vida alum paired a white, short-sleeved button-down with dark brown trousers for his handsome red carpet outfit.

Pitch Perfect star Alexis Knapp had a chic air about her as she walked the red carpet in a black jumpsuit with a teal, waist-cinching belt paired with dark sunglasses. 

The synopsis for the miniseries created by Haley Z. Boston reads: 'A certain atmosphere of horror is felt the week before the celebration of an unfortunate wedding.'

Morrone stars as Rachel Harkin while DiMarco plays Nicky Cunningham, her fiancé. 

The series follows the couple, who are set to be married in a week, as they travel to meet up with the rest of their family as a series of 'very bad' events occur. 

The rest of the Cunningham family comprises Leigh playing matriarch Victoria, Ted Levine as Boris, Wilbusch as Jules and Gus Birney as Portia. Fellow series regulars also include Karla Crome as Nell and Zlatko Buric. 

Something Very Bad Is Going to Happen premieres March 26 on Netflix. 

Hailey's outing in Los Angeles comes amid wild claims that her husband Justin Bieber got into a 'heated exchange' with his ex-mentor Usher at Jay-Z and Beyonce's Oscars afterparty on Sunday. 

Sources close to Bieber indicated it was Usher who approached the pop act with 'energy and anger' during the soiree at LA hotspot Chateau Marmont - but they insisted the dispute never became physical.

However, other insiders claimed the encounter culminated in a fistfight - leaving the exact nature of the alleged dispute unclear.

One source accused Bieber of having always been impolite to Usher, amid claims the Baby singer wants to freeze out people from his past, via TMZ.

Usher and Scooter Braun shepherded Bieber's rise to fame when he was 13 and 14, signing him to their label after winning a bidding war against Justin Timberlake.

Early in their respective careers, Bieber, 32, and Usher, 47, were also both the proteges of disgraced rap mogul Sean 'Diddy' Combs, 56.

Last May, Bieber firmly denied years of rumors that he was molested by Diddy as a child, with a spokesperson saying he was 'not among Sean Combs' victims.'

Among the star-studded guest list at Beyonce and Jay-Z's Oscars afterparty were Taylor Swift and Travis Kelce as well as Timothee Chalamet and Kylie Jenner.

Ryan Coogler and Michael B. Jordan were in attendance, as were Jacob Elordi, Teyana Taylor, Vin Diesel, Sofia Vergara, Austin Butler, Emma Stone, Emma Watson, Jon Batiste, Chloe Bailey and Vanessa and Natalia Bryant.

Bieber's wife Hailey, nee Baldwin, was also among the invitees, along with her longtime close friend and fellow supermodel Kendall Jenner. 

None of the famous names who dropped by Beyonce and Jay-Z's party has publicly discussed witnessing any spat unfold between Bieber and Usher. 

The Daily Mail has contacted Usher and Bieber's representatives for comment and has yet to hear back.
