I have no idea why that girl is so popular. She seems like a total dork to me. It just happens that the TV show she was on, was very popular. I didn't understand that one either. I had to pretend to sit through it with an ex girlfriend on numerous occasions, and I never once found it funny or appealing.
She reminds me of that "Katie.. whoever the hell", that had a baby with Tom Cruise. Who was that plain Jane looking chick? Where did she come from, and where did she go?
I suppose that anyone will gain tons of recognition if a star like Tom Cruise, or Brad Pitt, goes for a roll in the hay with them. That's about the only reason I can think of for her being so appealing.
