18. She's BFFs with Taylor Swift
Emma Stone is one of the hottest young actors around, so it's not too surprising that she's befriended one of the hottest young singers around. She talked about her friendship with Taylor Swift in 2011. "We met at the Young Hollywood Awards for Hollywood Life magazine," she explained. "We met there three years ago, and then I listened to some of her music, and I wrote her an e-mail saying I liked her music, I swear. And then we started talking and hanging out."
