However, we aren't surprised it has happened in this instance, as Sofia Richie has already been called out for somewhat morphine into Kourtney Kardashian, Scott Disick's ex and baby mama.
Now, Sofia and Kourtney have turned up to the same event in matching outfits, and we can't help but stare.
Attending the Malibu Chili Cook Off on Sept. 1, both girls wore white tank tops with high-waisted jeans.
It's unclear whether or not the two ran into each other during the event, however, Scott wasn't there, so there was probably no need for them to interact.
The girls both look pretty fire in their casual outfits, but who do you think wore it better?
