Justin Bieber and Selena Gomez hit a party in Paris together (ish)

Young love. So uncertain. So...crafty.

The ostensibly on-again Justin Bieber and Selena Gomez are both in Paris right now, and hit Carine Roitfeld's super glam CR Fashion Book party on Tuesday night. While they both wore designer duds and schmoozed with attendees (like the ever-present Kardashians), there is not one photo of them in the same frame, nor does anyone seem to know if the two hung out publicly together at all. Here's what we do know.

Selena wore a racy jumpsuit.

Kim Kardashian, Kendall Jenner and Kris Jenner were there.

This crazy moment happened:

Selena and Miranda Kerr -- who once inspired Bieber to take a swing at her ex, Orlando Bloom -- randomly (tellingly?) took a photo together. TMZ says Bieber steered clear.

Ciara was in the house.

Cara Delevingne wore this:

Justin met Karl Lagerfeld.

And everyone sang 'Happy Birthday' to Carine Roitfeld.

Specifically Kim, Kendall and model Gigi Hadid got on stage with the famous French editor and presented her with a cake.
