Sexy Celebrity Selfies: See Lindsay Lohan, Russell Brand, Amanda Bynes + More [PHOTOS]

Ah, the selfie. The most narcissistic thing on social media -- and the not-so-secret guilty pleasure of many. Celebrities, especially.

For the uninitiated (or Amish) among you, a selfie involves taking a photograph for oneself, not necessarily but most likely to get public adulation. The shots generally feature pouty duck lips, a state of partial undress or even complete nudity. (Bonus points if it's a mirror-pic with some lens flare.)
