If your name is KRISTEN and you're papped coming and/or going through an airport, ANY airport (and your name is Kristen), you're a famewhore.
If your name is KRISTEN and you're papped after you've had a fender bender and are trying to deal with that, you're a famewhore.
But announcing your engagement to the guy you've only been seeing for 2 months during a red carpet walk for an internationally aired awards show, pasting pictures of your fiance on your fingernails, then SELLING your wedding photos to a glossy gossip magazine? No. Not a fame whore at all.
