Justin Bieber sparked concern for his health on Monday as he broke cover for the first time since Diddy was indicted on sex trafficking charges last week.

Baby hitmaker Bieber's formerly close bond with disgraced Diddy has fallen under intense speculation since the indictment - with troubling videos of the pair emerging partying and a then-15 year-old Bieber spending '48 hours with Diddy.'

Bieber, 30, who recently welcomed a son with wife Hailey, has not publicly commented on the drama and looked cheery as he stepped out for dinner with his partner, 27, in LA - but fans quickly voiced fears over his 'thin' appearance.

The singer wore a grey hoodie, baggy jeans and fedora for dinner, completing his ensemble with shades.

New mom Hailey wore a leather coat and black trousers as she chatted with her husband four weeks after announcing the birth of their first child Jack Blues.

Bieber's appearance quickly sparked fears from fans who rushed to social media to express their concerns.

One wrote: 'He looks like he’s going through it . I don’t see happiness. Praying for him and what he went through.'

Another typed: 'He doesn't look healthy and that hurts my heart', 'Idk he look like he’s not well' and 'Justin looks rough. Maybe being a new parent is hard or that diddy stuff is really getting to him.'

Another follower penned: 'Justin don't look healthy ' and 'he is so thin.'

Several videos of Combs and Bieber have resurfaced in recent days following Combs' arrest.

One troubling clip saw Combs, who is 24 years older than Bieber, documenting his '48 hours' staying with the singer when he was just 15.

The mogul said: 'He's having 48 hours with Diddy, where we hanging out and what we're doing we can't really disclose. But it's definitely a 15-year-old's dream.'

He continued: 'I have been given custody of him. He's signed to Usher and I had legal guardianship of Usher when he did his first album.

'I don't have legal guardianship of him [Bieber] but for the next forty-eight hours he's with me and we're gonna go full crazy.'

Another resurfaced clip saw the rapper grilling a 16-year-old Bieber on why he hadn't been speaking to him as much.

'What's up man, you good? Selling out arenas and everything?' Combs asked the youngster.

'Starting to act different, huh? You haven't been calling me and hanging out the way we used to hang out.'

Bieber appeared anxious as he responded to his musical colleague.

'I mean you tried to get in contact with me throughout all my... and what not... but you never got my number,' he said. 'I'm going to tell you my number.'

 Another concerning video showed the pair partying in 2016 with footage which appeared to be taken at early celebrations for Bieber's 22nd birthday, showing the disgraced rapper presenting the youngster with a Bad Boy Entertainment bomber jacket.

Combs, now 54, is then seen putting his arm around the One Less Lonely Girl singer who held the garment up to the camera.

The pair proceeded to pose for pictures together before Bieber stripped off to put the coat on while the crowd around him cheered.

'Oh, he bad boy now,' an onlooker declared at one point in an apparent reference to the record label Combs founded.

Bieber's composure changes frequently in the clip, alternating between vacant and emotionless, to happy and dazed.

A later segment appeared to then show a bleary-eyed Bieber celebrating New Years with The Game, 44.

The troubling clip sparked concern among fans, with one posting on X: 'I feel so bad for he was just a kid.'

Another posted: 'This is really heartbreaking to watch!!'

A third asked: 'Does Justin Bieber even remember anything from that night?'

'This video makes me feel sick,' added another, while one concerned user posted: 'He looks out of it big time.'

Among the most shocking claims from Diddy's case is how federal agents seized 1,000 bottles of baby oil and lubricant from his Miami and Los Angeles homes during raids earlier this year.

They were used in 'freak offs' - 'elaborate and produced sex performances' that Diddy allegedly arranged and participated in - with 'baby oil' quickly trending worldwide and stunned fans posting memes.

It was recently revealed that Combs has 'been able to speak briefly to family members and his children via phone' as per People.

Diddy's phone call home came amid news his lawyers are not asking for him to be moved from the 'Hell on Earth' Metropolitan Detention Center in Sunset, Brooklyn.

'He is very concerned about his kids and their well-being,' the source stated. 

'He has three minor children, two of whom now have no living parent available with him incarcerated. Four of his seven children have neither parent available with him incarcerated.'

Another source said that the Combs kids are 'in a state of crisis and shock' following Diddy's arrest.

'It's heartbreaking to see the children in the state they're in. This is their father. But to them, he's not Diddy — he's Dad. He has always been a loving, devoted father.' 

He shares Christian, Jessie and D’Lila with the late model and actress Kim Porter, who died in 2018 at age 47.

Quincy was Porter’s son with partner Al B. Sure!, and Combs went on to adopt him.

He shares Justin with stylist Misa Hylton, and Chance with businesswoman Sarah Chapman.

In December 2022 he welcomed the arrival of his youngest child, daughter, Love, with model Dana Tran.

On Tuesday Justin, Christian, and Quincy arrived together at a New York City courtroom to support their father.

Combs’s three daughters and 23-month-old baby girl were nowhere in view.

Another source told People that Diddy is not getting any special accommodations at Brooklyn's Metropolitan Detention Center.

'He is being treated like any other detainee awaiting trial. As with all public figures in his position, he was placed on suicide watch upon admittance to the facility as a precaution.'

Diddy was arrested and charged last week for sex trafficking, racketeering and transportation to engage in prostitution.

The charge, which details allegations dating back to 2008, accuses him of abusing, threatening and coercing women for years 'to fulfill his sexual desires, protect his reputation, and conceal his conduct.'

He has pleaded not guilty to the charges.

Following his arrest, he was denied bail by a judge after he used both his and his mother's homes in Miami - worth $50 million - as collateral.

On Wednesday, he lost an appeal to overturn the decision and will remain in custody while pending trial.
