^ The Big Deal? Well, she's very known these past 3 years. Her songs are always in the top iTunes/Billboard charts & her latest 2 singles were Number 1 in the European Top 40 & Top 5 in the American Top 40.
And people are interested in her, mostly because of her looks... Especially teens.
I never listened to teen pop music ever, before I heard Selena Gomez & The Scene's songs like "A Year Without Rain" "Round & Round" "Love You Like A Love Song". . . Then I kinda fell in love with her! LoL.
