Remember when Demi said this.
"Selena is always there for me. Yesterday she was like, ‘You’re so pretty.’ When someone just randomly says that to you, it means a lot - especially if they know you have issues with that. We’re together almost everyday and she’s always making sure I’m okay."
and then at the Teen Choice Awards in 2011, you could see Selena told Demi: “you look so pretty” .
