BEIJING, May 11 (Xinhuanet) -- U.S. singer Katy Perry replaced actress Olivia Wilde to top Maxim magzine's 100 hottest stars list, media reports Tuesday.

Perry, 25, gained her fame in 2008 with No.1 single "I Kissed a Girl". She was engaged to British comedian Russell Brand last January.

"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," Maxim's editor-in-chief Joe Levy commented.

Last year's No.1 hottie Olivia Wilde, who was known for her character in "House", ranked only 20th on the new list.

From second to fifth on the list are supermodel Brooklyn Decker, "Avatar" actress Zoe Saldana, "Gossip Girl" Blake Lively, and "Transformer" hottie Megan Fox.
