LOS ANGELES, Aug. 11 (UPI) -- Justin Bieber is being linked to model Sofia Richie.
Bieber and Richie were spotted boarding a private plane at Van Nuys Airport. The singer will perform Saturday and Sunday in Chiba, Japan, as part of his Purpose tour.
The pair first sparked dating rumors with a playful outing Friday in Laguna Beach. They appeared at one point to be holding hands and were seen on a hike in the Hollywood hills the next day. Richie was also spotted leaving Bieber's home Tuesday morning.
"I've known him for a long time. I don't know if people really know that. I've known him for about, like, four years," she said of Drake to E! News in June. "He's a great friend."
Bieber released his fourth studio album, Purpose, in November and will bring his accompanying tour to a close Nov. 29 in London. Richie signed to a modeling agency in 2014 and was named the face of Madonna's Material Girl line the next year.
