The annual Maxim Top 100 Hot list for 2010 was released today by Maxim Magazine and there are some shocking surprises. “I Kissed a Girl” singer Katy Perry, who is engaged to her funnyman Russell Brand, was crowned the hottest woman on earth, dethroning “House” star Olivia Wilde. Really? Seriously?

“It’s that feeling you get when you suddenly realize that the smartest, funniest, coolest girl you know also happens to the best looking and a pretty good skateboarder, too,” mused Joe Levy, Maxim’s editor-in-chief. “All of sudden, your crush goes supernova, and this is Katy’s supernova moment.”
