Celebrities and syariah law

For those who have done the 2013 compre on celebrity fame recently, here's an example of celebrity embraced in activism, using their celebrity status to bring media focus on worthy issues. So do you still think celebrities are selfish and do not better the lives of others? Or could there still be a selfish agenda behind all these 'heroic' acts?
This is also a follow up on the implementation of the Syariah law in Brunei that I posted about some weeks back.

Qn: 'Celebrity and politics do not mix.' Do you agree?
