there are various ways to achieve the 'bling' you want - to get that specific look, you could do worse than get a star shaped brush or 'x' shape.

make star shape on a new layer, duplicate star layer, gaussian blur original layer (if u make copy of original layer, then turn it off, helps if you make mistakes [img]/infopop/emoticons/icon_smile.gif[/img] )switch back to top layer that is not blurred and change the layer mode to colour dodge or colour burn

without doing it myself i cant really think of a specific way of creating the 'bling' - some peeps may say stay away from the lens flare filter but used in conjunction with steps above could yield some ok results

And fig grew upon thorn
Some moment when the moon was blood, then surely I was born
