Beginwith a normal job for two people in different houses. Get them both all the skill points you can then get them to be very good friends with each other. Get them into the Fame career track. They will keep going up the ladder and will only need each other's Star power for the first couple levels. For example, if both have 2.5, then both need 2.5 to advance. They are friends though, and both have 2.5 Star friend power.
