While they could have been blond sisters on Sunday night, their mutual journey from ethnic babe to Beverly Hills Blah has been years in the making.
Here's J Lo and Bey, in 2005 and 2008, respectively:
Clearly, Bey is the copy-cat in the bouffant hairdo, black dress competition. What about the mermaid look?

Uh-oh, look at this one:
This time, Jennifer was one year before Beyonce in the straight dark hair, white dress look.
Is imitation the sincerest form of flattery? Or is it all just a happy coincidence that the two superstars are evolving together in sync?
You decide. Meanwhile, here they are at the starting line.
