Ke$ha: '7 Hollywood' Inside Feature (Exclusive)

Ke$ha rocks spiky hair in the inside photo spread for 7 Hollywood‘s Icons issue, on newsstands now.

Here is what the 25-year-old singer had to share with the mag:

On writing the Britney Spears hit “Till the World Ends”: “It still is, like, kind of one of my proudest moments as a songwriter because there’s something different about it. When I write a song for me, that’s one thing. But when I write a song for someone else, especially one of the biggest pop stars that has ever lived and is an icon, I don’t really know if it could get much better.”

On changing her music and style: “Don’t worry, I’m not going to sell out or anything. But I do think that there’s a way to mix high fashion and vintage. I tried a little bit of the influence of the kind of music I like to listen to in my spare time and mold, meld it with the kind of music that I’m known for making. So they’re still, like, really fun party anthems, but you’re just going to hear a little bit of my influences in there.”

FYI: The spread was shot by photographer Alix Malka.
