Isn` t it everywhere that public or famous people will try to promote themself ?
If that` s what she is famous for and when people are interested in her then i think its ok.
Also what works all the time is "sex sells".
That` s just the society we` re living in, driven by double morals.
So even if we like it or not, the mass seems to like it a lot. Else they simply could stop voting her posts up.
