Meeting "Celebrity" what do I say?

I'm going to an event in the days where one of my favourite radio dj's is going to be. I'm kinda nervous about meeting her, because I don't know what to say. I don't want to say the cliche, stereotypical "I've loved you for so long" or "You inspired me to go in to radio". I want to say something memorable, smart and funny. I know this is a silly question, and I'm probably thinking too much, but I appreciate suggestions!
