This is a total different thing I think you have mistook that to be love but it is not love when love happens it is uncontrollable because whatever you do you see yourself drawing close to the person without knowing.
example: we dont want to date ugly girl so we look for beautiful lady.
that guy is handsome and rich i love him
This example you gave is just called gold diggers who love for a reason and what they can get in return from the victim and when this is gone when there is no money and no fame then you'll see them backing away slowly from what they claim is love.
That was just love for money and not genuine love.
