10. Katy Perry
Katy Perry is undoubtedly one of the hottest and most beautiful singers around. She is a free-spirited soul who shows no inhibitions whatsoever to let everyone know what’s in her mind or even her body for that matter. The ‘Teenage Dream’ singer turned down the Playboy Magazine offer and while it is a big disappointment for all us, that didn’t stop us from imagining her in the ways we can’t really talk about.
