Bieber shared a selfie of the two sitting in the back of a car. The 22-year-old pop star was sporting some scruff, his nose ring and a black T-shirt, while Richie rocked a chic cheetah-print jacket and red bandana, keeping her hair pulled back in a trendy top knot.

A few hours earlier, he shared a black-and-white snapshot of the two. Bieber was shirtless in the background, while Richie hit the Dab, a dance move made popular by the likes of NFL pro Cam Newton, rapper Rich the Kid and Jason Derulo.

"Dab on em," Biebs captioned it.

Richie, who is the 17-year-old daughter of Lionel Richie and younger sister of fashionista Nicole Richie, joked "no pictures" in the caption of one of her Instagram photos, where she was wearing a sweatshirt emblazoned with the "Sorry" singer's face.

Another photo showed Bieber wearing a goofy hat.

The model also took to Snapchat to show off her toned abs, using the app's Chūō, Japan, geofilter.


And it looks like she had a blast watching her rumored boyfriend "killemmm" on stage at the Makuhari Messe convention center.


Bieber and Richie have yet to comment on whether they're officially a couple or just good friends, but the two have been spending a lot of time together as of late.
