From AOL News:
"She feels that she's young and she wants to make sure it's right," actress Kyle Richards, Hilton's aunt, tells PEOPLE. " She didn't want to make a mistake with the whole world watching."
Oh no! Paris is certainly not one to make mistakes with the world watching!!
(Note: If you don't get sarcasm and/or have been living under a rock for the past year, I've compiled a sample of 'mistakes' she's made with the world watching just for you. Not Safe For Work!)
It is a shame when you think about it though. Think of the tremendous fashion sense their children would have had...
