Justin Bieber tried to keep a low-profile while out solo in New York City amid growing fan concern over his mental well-being and marriage to wife Hailey Bieber.

The Grammy Award-winning singer, 30 — who enjoyed a date night with his wife of six year earlier this week — appeared to prioritize his wellness by heading to a spa in lower Manhattan on Wednesday.

Wearing the hood of his pale yellow sweatshirt up over his head, Bieber made a beeline for the spa’s entrance.

Bieber appeared to be shirtless beneath his sweatshirt, which he left unzipped to expose his heavily tatted chest.

He further disguised himself by sporting large, black sunglᴀsses and a blue beanie over his blonde hair.

Bieber completed his spa day outfit with baggy cargo pants that sat low on his waist, exposing his navy blue boxers, and a pair of fuzzy brow slippers.

The Baby hitmaker — who a source recently told DailyMail.com is a ‘loose cannon’ — carried his blue iPhone in one hand and a baggy of candy, a cord and his wallet in the other.

He was later seen leaving the popular spa with his jacket unzipped, exposing his shirtless torso. 

While Bieber was without his wife Hailey on Wednesday, the couple were spotted grabbing dinner in NYC on Tuesday night.

Speculation about their relationship has intensified, particularly in light of reports describing Justin’s behavior as ‘unacceptable.’

However, the couple seemed unfazed as they made their way into The Corner Store for dinner. 

Despite the romantic gesture of a dinner date, Justin’s downcast demeanor seemed to reflect the growing speculation surrounding his reportedly ‘unacceptable’ behavior, which has allegedly put a strain on their six-year marriage.

Last Thursday, the couple had already set tongues wagging when they were seen separately at the popular restaurant Bar Pitti. 

Hailey was spotted leaving alone around 4:30 PM, while Justin arrived with a group of friends just half an hour later, before exiting solo at 6:40 PM.

Sources close to the couple have since revealed to DailyMail.com that Justin’s weary look may be the result of him becoming ‘borderline reclusive,’ struggling with the pressures of large crowds and the constant spotlight after years in the public eye.

‘Justin has been struggling for the last couple of years and a significant part of that is down to his worry about being in certain public situations,’ the source said.

‘He has built up a deep fear of being out in spaces with lots of people and has a deep-seated worry about large crowds.That is one of the reasons why he’s not done any touring for a while.’

‘Justin focused on trying to heal and get better by staying away from too many outings away from his homes where he would have to mix with strangers – and that in turn has made him borderline reclusive at times.’

His fears have taken a toll on Hailey who has been desperately trying to encourage him to overcome his concerns, with the insider claiming their recent trip to Aspen was her attempt to help ease him into public life.

This report comes just days after the couple – who share son Jack Blues Bieber – appeared to present a united front, enjoying a date night together over the weekend.

However, sources tell DailyMail.com that Hailey’s friends are growing increasingly concerned about Justin’s ‘unacceptable behavior,’ with some reportedly urging her to leave the musician.

‘Hailey’s been struggling with Justin almost since the start of the marriage,’ an insider told DailyMail.com exclusively last week.

‘She loves him madly but he’s a loose cannon. Some of her friends have advised her to go it alone and leave him,’ the source shared.

‘His behavior is sometimes unacceptable. She’s put up with a lot.’

The insider said Hailey and those close to her were hopeful that he would change after the arrival of their first child, son Jack Blues Bieber, in August 2024, but despite being there for her, little has changed.

‘When the baby was born he was there for her and she thought being a father would change him for the better, but it hasn’t stuck,’ they added.

Last week, Justin also attempted to debunk rumors of marital woes between him and his wife after setting the record straight about unfollowing her on Instagram.

Just hours after insisting that his social media account was hacked, he returned to the app to share loved-up pH๏τos with Hailey from their trip to Aspen, Colorado.

Mystery surrounding the couple’s marriage has intensified ever since he unfollowed his father-in-law Stephen Baldwin, furthering speculation of relationship woes and concern for the star after he also shared a picture of a bong.
