If you find yourself humming 'We Are the Champions' the next time you stroll past the perfume counter, thank Katy Perry.

Perry's new fragrance, dubbed Killer Queen, was inspired by -- you guessed it -- the music of Queen. As Perry recently told Women's Wear Daily, she's been a fan of the band for a long time, and the song 'Killer Queen' had a particularly profound impact on her teenage years.

"Freddie Mercury painted the lyrics of this woman who I wanted to be," Perry explained. "She seemed very powerful, and she captivated a room when she walked in. I named my company Killer Queen after those lyrics. I feel like, after all this time, it was appropriate to use that name in association with something I did. I feel like I’m falling, finally, into that woman Freddie painted."

Something tells us Mercury would get a kick out of Perry's take on his song, which served as the band's breakthrough hit when it was released in 1974. "It's about a high-class call girl," he explained in a 1974 interview. "I'm trying to say that classy people can be whores as well. That's what the song is about, though I'd prefer people to put their interpretation upon it -- to read into it what they like."
