He seems to go through girl after girl and when he's done with them, it's only a matter of time until he's spotted with them again.
This time, it looks like he's ~tuning~ his former flame, Sofia Richie.
It's almost been a year since the pair enjoyed their whirlwind romance and now the Biebs is going back for more.
The 18-year-old took to Insta to post a fiyah selfie with pizza because who wouldn't want a photo with pizza?
She captioned the pic "happy place" for obvi reasons.
Eagle-eye fans then noticed that the uber romantic Justin wrote: “You are gorgeous!!” in the comments.
Justin's got his flirty pants on!
Although we wonder how Sofia feels about this, especially considering any form of attention from Biebs ends with her getting swarmed by fans.
Everyone needs to chill out and let these crazy kids be happy, plz.
