Justin Bieber revealed his striking weight loss as well as a mystery injury as he stepped out in Hollywood on Friday.

The singer, 31, who sparked concern with an online rant earlier this week, cut a slighter figure and sported a knee brace on his left leg as he headed to a spa.

A somber Bieber flashed his neck tattoo in two hoodies, paired with a baseball cap and green check print shorts.

He completed his ensemble with blue sliders.

The star has not publicly commented on his knee injury.  DailyMail.com has contacted a representative for Justin Bieber but did not immediately hear back.

This comes after the Baby hitmaker sparked concern after going on an impromptu Instagram rant on Tuesday.

Justin Bieber revealed his striking weight loss as well as a mystery injury as he stepped out in Hollywood on Friday

The pop star took to Instagram in a bizarre post to share his thoughts about telling other people what they do or do not ‘deserve.’

‘Telling other humans they deserve something is like raising someone else’s kids,’ he wrote in his latest post. ‘Who are you to tell someone what someone should or shouldn’t have?’

He balked at ‘the audacity’ and slammed his fans’ unsolicited opinions: ‘That’s not your place. God decides what we deserve.’

In response to his post, fans flooded his comments section with messages voicing concern, calling out his ‘hypocrisy’ and urging him to ‘take a social media break.’

Many fans seemed to believe he was responding to recent fan comments telling his wife Hailey Bieber, 28, that she ‘deserves better’ after his ‘disrespectful’ posts towards her.

This comes after fans criticized his ‘Mother’s Day sucks a**’ post on his wife’s first Mother’s Day since they welcomed their first child, son Jack Blues Bieber, in August 2024.

They also pointed out that he recently admitted he previously told Hailey that she would ‘never’ land a Vogue cover in a since-deleted caption meant to congratulate his wife on that same, recent accomplishment.

He also shared the post to his Instagram Story accompanied by Lil Tecca’s song OWA OWA, in which he raps about pleasuring his partner and ‘making it clear to his significant other that his time and presence should not be taken for granted,’ per Genius.

One fan commented on the Peaches singer’s post and wrote: ‘Justin. You told Hailey she couldn’t be on a cover of Vogue, isn’t that telling her she can’t have something?’

‘Didn’t you just tell this girl she couldn’t be on Vogue,’ another fan wrote.

Similar comments flooded his post. One person asked him: ‘Brother didn’t you tell your wife she could never be on the cover of Vogue???’ Another person added, ‘Take a break from social media, Justin.’

‘I think you should leave God out of this and grow up,’ one Instagram user penned.

‘God told me you need a social media break,’ another fan commented.

‘Crashing out online is the worse,’ a fan commented about his rant and recent controversial social media posts.

‘God forbid a girl tell someone they deserve to be happy,’ another user added, seemingly referencing Selena Gomez’s recent cryptic posts.

The singer’s ex shared recent posts with interesting timing about ‘cheering’ people on and wishing she had the ‘ability to erase one person’s greatest pain.’

The former Disney star’s social media posts have recently sparked fan speculation that she was secretly sending messages of support for Hailey.

‘Justin you need some therapy bro,’ another user commented while one fan added, ‘Bro this is not twitter.’

One user wrote: ‘My boy crashing out again?!?’

Justin’s recent post comes amid concern about not only his marriage but his mental wellbeing regarding his increasingly bizarre behavior.

After Hailey’s Rhode beauty brand was acquired in a $1 billion deal last week, many fans started telling her to divorce Justin now that she has found fame and fortune on her own.

Though many of the posts were apparent jokes, the couple have been entangled in rumors of marital woes while Justin has been on the receiving end of substantial backlash.

The pair have been married nearly seven years after they tied the knot in 2018.
