Justin Bieber's health raises concerns as he appears thin and tense amid new Diddy allegations

Justin Bieber appeared thin and tense on Monday evening as he and his wife, Hailey Bieber, marked the fifth anniversary of their 2019 wedding.

The sighting occurred amidst growing concerns about the 30-year-old singer's health, with rumors swirling about his previously close relationship with disgraced rapper Sean 'Diddy' Combs, 54.

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

Since Combs' arrest on September 16, more disturbing accusations have emerged, including claims of abuse involving a nine-year-old.

To celebrate their anniversary, Justin and Hailey, who became parents in August, had dinner at Baltaire Restaurant in the Brentwood area of Los Angeles.

As they left the restaurant, Hailey, 27, seemed to be looking out for Justin as she walked ahead of him, with security following close behind.

Rather than her usual stylish attire, the Rhode skincare CEO opted for a more casual look, wearing an oversized beige sweater, jeans, and black loafers.

She accessorized with red-framed glasses, and her dirty blonde hair was pulled back in a claw clip.

Hailey also carried a leopard-print bag on one shoulder as they swiftly headed to the valet.

Justin maintained a serious expression as he left the restaurant, sporting black sunglasses and a baseball cap pulled low over his face.

In response to fan concerns about his visibly slimmer appearance, the "Baby" singer concealed his figure under a loose-fitting black leather jacket, pants, and sneakers.

The couple was accompanied by several male security personnel.

Justin did not publicly acknowledge their wedding anniversary on social media on Monday.

Meanwhile, Hailey celebrated the occasion by sharing throwback photos from their 2019 wedding in South Carolina.

The lavish ceremony took place one year after the couple officially wed at a New York City courthouse on September 13, 2018.

Hailey posted photos on her Instagram Story, showcasing the wedding dress designed by the late Virgil Abloh for her special day.
