After looking at these pictures, we think we know the answer!
The besties have been copying each other's looks for a long time.
Most recently, Ciara was snapped wearing the same black ruffled Cavern dress Kim wore last month in Paris.
And last year the twosome wore the same silver Brian Lichtenberg dress, only it was Kimmy who copied the singer.
We just hope they don't show up to the same event in the same thing. That would be awkward!
