Paris Fashion Week may have wrapped for this season, but it looks like Justin Bieber's not done with the City of Light just yet. So far he (and his mustache) have changed into three outfits in one day, had dinner with Kendall Jenner, and most recently, met Karl Lagerfeld! Yep, saggy pants enthusiast Justin Bieber wagged chins with Chanel HBIC Karl Lagerfeld at the CR Fashion Book Issue No. 5 launch party.

You, much like us, are probably wondering: What were the events leading up to this fortuitous photograph? What intelligent discourse might've transpired between these two icons? Well, it took some work, but we came up with a list of potential conversation topics for this unlikely duo.

Kendall Jenner

Jenner and Bieber had dinner together. Kendall walked Lagerfeld's Chanel Spring/Summer 2015 show. It's a no-brainer! Also, it leads to...

Feminism

We already know that Lagerfeld's a #HeForShe advocate, but what about Biebs?

The Apple Watch

Lagerfeld might be fashion's biggest Apple fanboy, and just yesterday, he attended a special one-day event at Colette mere hours before his Chanel show. Biebs is a tech investor and promotes a grip of apps.

The Weather

Look, sometimes making small talk is hard, OK?

Saggy Pants

Whether you're a fashion designer or not, it's hard NOT to comment on Bieber's love of saggy pants. But also, it's very topical.

Selfies

Bieber's Instagram is plastered with self portraits, whereas Lagerfeld has gone on record with Women's Wear Daily about his distaste for selfies: "And what I hate most in life is selfies." And yet, this selfie exists. How did Biebs convince Uncle Karl? The world may never know...

We're hoping this leads to more meeting of the minds between these two, or at the very least an unlikely bromance. Lagerbiebs? I ship it.
