Crooner: Justin Bieber bared his musclebound torso as he went shirtless for a surprise performance on night one of Coachella

Justin was wearing a set of denim sweats that sagged low enough to reveal the hemline of his Calvin Klein underwear.

The STAY singer, who has famously underwear modeled professionally for Calvin Klein, accessorized his look with earrings and a baseball cap.

Earlier in the evening he had been spotted heading through the fairground, concealing his taut torso in a tank top and a crimson PVC jacket.

This year’s Coachella line-up featured a massive change as earlier this month it was announced that The Weekend alongside Swedish House Mafia would be replacing Sunday night’s headliner Kanye West.

The Weeknd and the house music group – consisting of Axwell, Steve Angello and Sebastian Ingrosso – have a working relationship as they collaborated on hit track Moth To A Flame together and also have the same management team SALXCO.

It remains unclear how the headlining gig will work meaning whether one will perform after the other or if they will be switching off but the publication’s sources said The Weeknd’s portion will likely be shorter given the time restraints to prepare for the show.

Top man: It was announced earlier this month that The Weeknd (seen at the Super Bowl in February 2021) will fill Kanye West ‘s headliner spot at this year’s Coachella after the rapper decided to pull out of the festival just two weeks before kick off

This will also be Swedish House Mafia’s big return to the highly-popular music festival as they have not performed at it since 2012 as they disbanded in 2013 at their absolute peak of popularity.

The Weeknd first hit the Coachella stage in 2012 and then three years later in 2015. He officially headlined the festival in 2018 with Beyonce and rapper Eminem.

Rapper West, 44, was set to co-headline the annual festival with Billie Eilish and Harry Styles, both of whom are considered pop/alternative acts, as well as house music group Swedish House Mafia.

Organizers were scrambling to salvage the long-awaited festival after West announced earlier this month that he’d no longer be performing.

West is said to have made the decision himself to bow out from the two weekend even.

Travis Scott was said to be appearing with Kanye – who has changed his name to Ye – and will also no longer perform, the outlet reported.

Scott had been tapped as the headline act for the festival 2020 before it was canceled due to COVID. He was then booked again for 2022 but organizers scrapped those plans after his Astroworld concert tragedy that left 10 people dead.

It remain unclear exactly why Ye had pulled out of the show so last minute. A source has claimed to Variety that West had not rehearsed or prepared for the appearance.

West’s last-minute drop out came months after he was banned from the Grammys for his ‘concerning online behavior’ and attacks against ex-wife Kim Kardashian and her boyfriend Pete Davidson.

He’d also published several offensive posts to Instagram about this year’s Grammys host Trevor Noah, which prompted the social media platform to suspend his account for 24-hours for violating their terms of service.

Even beside the headliners it is a star-studded line-up as Doja Cat, Megan Thee Stallion, Lil Baby, Daniel Caesar, Phoebe Bridgers, Disclosure, Jamie XX, Run The Jewels, Big Sean, Karol G, Maggie Rogers, 21 Savage, and famed composer Danny Elfman are all set to perform.

Back in January 2021 it was announced that the highly-popular music festival in Indio, California would be returning in Spring 2022 after two years of rescheduling due to the COVID-19 pandemic.

One of the world’s largest musical festivals, the event has been held every spring in the Coachella Valley in the Colorado desert since 1999.

After being pushed back due to the pandemic, the festival announced its long awaited return on New Year’s Day 2021 with a simple tweet that read: ‘See you in the desert’

When the coronavirus pandemic hit the US last year the festival rescheduled from April 2020 to October 2020, before being outright cancelled for the first time in 20 years that June.

The Coachella 2020 lineup featured Frank Ocean, Rage Against the Machine, and Travis Scott as headliners, with a full lineup including Lana Del Rey, Lil Uzi Vert, Thom Yorke, Run the Jewels, Danny Elfman, FKA twigs, DaBaby, 21 Savage, Caribou, Lil Nas X, and more.

The festival was then rescheduled for April 2021 before being canceled again in January after California’s public health officer ordered Coachella to cancel the event due to continued concerns over COVID.
