Kirk Cameron was a typical teen star in the 80's. But since then he has become "born again", and he has demonstrated with his actions as well as his words, that he is no longer interested in the "typical Hollywood star" lifestyle and is primarily committed to his religious convictions.
So based on this, no, I don't think it's sad that he is not having a glamorous party. He has the right to choose what to do with his life, and he has chosen living modestly and following his religious beliefs over pursuing fame.
(Hope this does not violate any EHell rules -- I know religion can be a sensitive subject, but it really is the elephant in the room here, especially since it says the photo is taken at a ministry.)
