I don't think it's about celebrities at all actually. In fact, I think really it's talking about letting go. Either you do what you want or you conform to society - "Yeah, it's overwhelming but was else can we do: Get jobs in offices and wake up for the morning commute." It's the cliche of the 9 to 5 work day.
Then when they say. "The models will have children, we'll get a divorce
We'll find some more models, everything must run it's course. " It means that no matter how much we try to be different we are exactly the same as everyone else. Either were fated to pretend by doing the socially acceptable or we pretend to enjoy to be an outcast. No one is truly happy.
