2. Elle Fanning

Elle Fanning

Born on: April 9, 1998

Hottest Teen Celebrity because: I can't believe this gorgeous girl is only 13! We once knew her as Dakota Fanning's little sister but with each passing day, she proves that she is a force on her own and is as talented as her sister if not more. Every time I see a new photoshoot with Elle, I'm left with my mouth wide open. She's not only #beautiful but has an adorable sense of style and is incredibly grounded. Do we need any more reasons to add her to this list?
