This is an early picture of Max and Emme, back when J.Lo couldn't tell them apart.  Things have changed.  Jennifer Lopez has dropped a bit of knowledge on us as to how Max and Emme each differ from the other.  If you're thinking about having fraternal twins you may want to take notes.

Lopez told the U.K. version of Ok! Magazine that she can spot Emme because "her hands are very feminine. And she has more hair than him.”

Max on the other hand?  “He is like a tank, with these little arms.”

That there is called motherly intuition.  I don't know what Marc does, but I'm guessing the same thing I would do:  Max has a penis and Emme doesn't.  Men are simple like that. 

If you really want to test your skills at telling the Lopez twins apart here is a picture for you:
