Justin Bieber was spotted enjoying a dinner date with a mystery woman at The Peppermint Club in Hollywood on Monday. He was even photographed giggling with his brunette date while both of them were looking at her phone screen.

Bieber exposed by Instagram hackers

But before he stepped out with a mystery woman, the Canadian singer's nude photos landed on Selena Gomez's hacked Instagram account [VIDEO]. The said photographs were taken from Justin Bieber's Bora Bora getaway with then-rumored girlfriend Jayde Pierce in 2015.

The NSFW images featured a completely naked Justin Bieber outside his villa. The "Love Yourself" artist explained that the paparazzi photos were published without his approval.

Hence, he felt "super violated" that his privacy was invaded. “Like, I feel like I can’t step outside and feel like I can go outside naked,” he added.

His nude photos on Selena Gomez's Instagram account earned more than 30,000 likes before the profile was set to private. After a few minutes, the "Fetish" singer opened her profile again to her 125 million followers without the explicit post.

In a statement released by Instagram on the hacking incident, it confirmed that one or more perpetrators obtained illegal access to the contact information of some high-profile users. The photo-sharing platform explained that the people behind the incident used a bug to perform the hacking.

"Our main concern is for the safety of our community and, out of an abundance of caution, we are reaching out to all verified accounts," Instagram stated.

"At this point we believe this effort was targeted at high-profile users."

Singer accused of receiving STD treatment

After his nude photos resurfaced on the internet due to the hacking incident, Justin Bieber was linked to another controversy wherein he was accused of receiving an STD treatment several months ago. The issue came after a hospital staffer complained about her immediate termination from Northwell Health for allegedly peeking at the singer's medical records.

According to TMZ, Kelly Lombardo reportedly checked Justin Bieber's hospital records out of curiosity after she was told that the pop singer was admitted to get an STD (sexually transmitted disease) treatment.

"She was told, 'You are a young female, you're not curious about what he was doing in the ER?' And they fired her," her attorney said.

Several sources, however, denied that the "Cold Water" singer was admitted for an STD case [VIDEO]. Meanwhile, Justin Bieber was all smiles during his first public appearance since these issues came out. Dressed in a red shirt and black shorts, the 23-year-old artist smiled at the camera while leaving Il Pastaio in Beverly Hills.
