Fashion Design Reality Shows

Do reality show stars get paid to live their life?
For example: Do The HIlls girls get to work at their jobs AND just to have cameras follow them? what is their primary job? the fashion design industy or actresses? Someone please explain!
if its really reality then they arnt acting they sign contracts for the show and they get money for that season it isnt for living their lives its for taking part in the show
and they do get paid in their job at the industry they pay them there too
their primary job well reallly you would have to ask the person
