I found Zooey to be attractive in Elf. Didn't care for the song so much, but was very impressed by her vocal talent.
I think she was also in that movie with Tim Allen and Johnny Knoxville, forget the name. She looked very pretty in that too but a bit young.

Anyway, they're both pretty, and I do kind of like "I kissed a girl" (more so a remix of it), but I'd also say Zooey (is that really how she spells her name :ugh comes out on top.
