Justin Bieber looked gaunt and tense on Monday night as he and his wife Hailey Bieber celebrated the fifth anniversary of their 2019 wedding.

The sighting comes amid fears for the 30-year-old singer’s, 30, health as rumors continue to circulate about his once close relationship with disgraced rapper Sean ‘Diddy‘ Combs, 54.

Combs is currently sitting in a New York City jail after being arrested on sex trafficking charges last month.

Since the September 16 arrest, more shocking allegations have been made against Combs, including the alleged abuse of a nine-year-old.

For their anniversary, Justin and Hailey — who welcomed their first child together in August — dined at Baltaire Restaurant in Los Angeles‘ Brentwood neighborhood.

As they exited the restaurant, Hailey, 27, appeared protective of her spouse as she walked several feet in front of him while their security remained in tow.

Instead of her typical glamorous style, the Rhode skincare CEO, 27, kept it low-key for their dinner in an oversized beige sweater, jeans and black loafers.

She had on red-framed eyeglasses and her dirty blonde hair was swept up in a claw clip.

Hailey kept a leopard-print bag over one shoulder as they quickly made their way to the valet.

Justin looked stoic as he emerged from the restaurant wearing black sunglasses and a baseball cap low over his eyes.

In wake of fans calling out his noticeably thinner appearance, the Baby hitmaker hid his body under a baggy black leather jacket, pants and sneakers.

The couple were accompanied by several male security guards.

Justin did not publicly acknowledge his and Hailey’s wedding anniversary on social media on Monday.

Meanwhile, Hailey paid tribute to the milestone by sharing throwback photos from their 2019 nuptials in South Carolina.

The star-studded ceremony was held one year after they’d tied the knot in an NYC courthouse on September 13, 2018.

Hailey uploaded photos to her Instagram Story of herself wearing the wedding gown that the late designer Virgil Abloh designed for her special day.

The off-the-shoulder number featured a long train and was notable for its its pearl and lace touches with the slogan ‘Till Death Do Us Part’ emblazoned on the veil.

‘Happy Birthday V, we miss you! Thank you for making me the most magical wedding dress,’ Hailey captioned the post.

Justin and Hailey’s tense outing on Monday comes amid reports that the former child star is determined to block out growing rumors about his connection with Combs, choosing instead to focus on his role as a first-time dad.

Combs was arrested in New York on September 16 on charges of coercion and abuse.

Following the indictment, Justin’s past close relationship with the rapper has come under scrutiny, with resurfaced videos showing a 15-year-old Bieber spending ’48 hours with Diddy’ and partying together.

Bieber hasn’t addressed the situation publicly, but fans have expressed concern about his noticeably ‘thin’ appearance.

Now sources tell DailMail.com that the singer feels he has no one to talk to about the Diddy revelations and is ‘sailing these waters alone.’

‘Justin feels like there is no one that he can talk to that understands and, to be honest, he doesn’t even fully understand,’ the insider explained. ‘He was a kid.’

The source added that the fallout comes amid his current struggles to try and be a good parent having not had the best example from his own father, Jeremy Bieber.

‘Justin is stressed right now,’ the insider continued. ‘He has a baby boy and trying to be a good dad without having anything to reference what a good father is.’

Speaking to the fragile singer’s emotional state, the source added: ‘He is sailing these waters alone and everyone fears that if Hailey shows any struggles with being a first time mom then this is going to be incredibly difficult for Justin.

‘Diddy could not have happened at a worse time as he is trying to experience the joy of being a father with the pain of having to deal with all of this.’

Bieber announced the birth of his first child on August 23, and gave fans a glimpse of the baby’s tiny foot and wife Hailey’s hands.

‘WELCOME HOME JACK BLUES BIEBER,’ the proud dad penned in the caption.

The former Victoria’s Secret model also shared the post on her Instagram Story with the youngster’s name and various emojis.

It came just weeks before Combs was accused of inducing female victims and male sex workers into drugged-up, sometimes days-long sexual performances referred to as ‘Freak Offs.’

According to the indictment, he would allegedly use force, threats and coercion to get the women to engage with male sex workers in the ‘Freak Offs,’ described as ‘elaborate and produced sex performances’ arranged and directed by Combs while he masturbated and often recorded them.

The indictment further stated that some ‘Freak Offs’ would last for days, requiring Combs and victims to receive IV fluids to recover from the exertion and drug use.

Diddy pleaded not guilty to charges against him and was denied bail, despite his legal team’s request for him to be released for $50 million and kept electronically monitored.

Combs’ lawyer, Marc Agnifilo, said the ‘Freak Offs’ stemmed from the star’s former on-again-off-again relationship with R&B singer Cassie, and were not coercive.

Prosecutors said they had interviewed more than 50 victims and witnesses, and are expecting the number to grow.
