Men are simple creatures -- drop hints that you might have made out with a girl and guys will line up to buy whatever you’re selling. Katy Perry found this out after releasing her album, One of the Boys, early in 2008. Her song “I Kissed a Girl” became a hit and thrust this sultry singer into the spotlight. The intrigue around her sexuality, coupled with her rather unique fashion sense, make her one of the most interesting girls on this list. She’s got sass, personality and isn’t afraid to speak her mind -- add in the No. 1 hit and you’ve got one up-and-coming superstar.
