Justin Bieber and model Sofia Richie have sparked romance rumours as they have been spotted spending a lot of time together after being pictured holding hands on Laguna Beach on 5 August. Now, the duo have reportedly flown to Japan where the Sorry hit-maker is scheduled to perform on his Purpose Tour on 13 August.

According to The Mirror, the singer and the 17-year-old were spotted boarding a private jet at Van Nuys airport on Wednesday (10 August). Earlier in the day, the two were seen hiking. Bieber showed off his tattoos in a white tank top and blue shorts, while Richie was dressed in a pair of leggings, an oversized t-shirt and white sneakers.

The younger daughter of legendary singer Lionel Richie was pictured leaving Bieber's Toluca Lake home on the morning on 9 August, a few day after their leisure walk on Laguna Beach.

According to The Daily Mail, the 17-year-old model was apparently waiting for her ride outside Bieber's home. Sofia was wearing a sports bra and pajamas as she left the singer's place in a Mercedes, it reported.

Bieber earlier in the month made headlines after nude pictures of him hit the internet. The photos of the singer were from his Hawaii vacation with Sahara Ray. The model's semi nude photos also did the rounds at the time.

This is not the first time Bieber has gone nude. In July 2015, the singer shared a photo on Instagram that showed off his backside. However, the singer later apologised for posting the photo.

"Hey, I Deleted the photo of my butt on Instagram not because I thought it was bad but someone close to me's daughter follows me and she was embarrassed that she saw my butt and I totally wasn't thinking in that aspect. And I felt awful that she felt bad. To anyone I may have offended I'm so sorry," the singer wrote alongside a photo of himself fully clothed. (via MTV news)
