Maxim's Hottest is ... Who?

Katy Perry was named Maxim's hottest woman this year. To which I ask - who is she? I have never heard of Katy Perry. And when I see her photos, I don't know why they picked her number one. She seems quite plain to me. (Sorry, just being honest.) I like Kim Kardashian as my number one. And I don't even see Shakira on the top 100 list. What's with that?
