Curvaceous singer Katy Perry has come out on top of Maxim's 'Hot 100' list, touted by the popular men's magazine as "the definitive list of the world's most beautiful women." Perry beat out the likes of other beauties such as actresses Zoe Saldana and Megan Fox, and reality television star Kim Kardashian.

Maxim's Editor-in-Chief Joe Levy explained to Access Hollywood that her appeal lied beyond skin deep. "We interview the world's most beautiful women all the time and they always tell us, 'I like a guy who's funny,' but here's one who's not lying," said Levy, referencing the singer's engagement to British funnyman Russell Brand. Levy calls Perry topping the list as a "supernova moment". "It's that feeling you get when you suddenly realize that the smartest, funniest, coolest girl you know also happens to be the best looking and a pretty good skateboarder, too."

Coming in second and third place is tennis hotshot Andy Roddick's wife, Sports Illustrated swimsuit model Brooklyn Decker, and Saldana, who has scored herself a number of blockbusters since last year by appearing as Uhura in 'Star Trek' and 'Neytiri' in James Cameron's 'Avatar'.

Saldana saw a noticeable jump from last year's #29 ranking. "To be perfectly honest, 'Avatar' is awesome - but she's Uhura," said Levy. "Let's not forget - we're nerds. So you know, sexy 'Star Trek'? Need I say more?"

Rounding up the top ten are, in order, 'Gossip Girl' Blake Lively, Fox, singer Rihanna, George Clooney's latest arm-candy Elisabetta Canalis, Olivia Munn, Kardashian, and Victoria's Secret Angel Marisa Miller.
