Justin Bieber Calls Girlfriend Selena Gomez the "Girl Next Door"

Justin Bieber can't say enough positive things about his leading lady Selena Gomez. The teen dream couple displayed their love all over the Teen Choice Awards Sunday night, and Justin raved about Selena and her mass appeal.

"Best performance of the night, Selena Gomez," Justin told MTV News on the TCA blue carpet, predicting Selena would stun with her performance of "Love You Like a Love Song" — and she did just that! (Justin even sang along with Taylor Swift during the performance!)

Selena even took home an award for the ditty with her band The Scene for Choice Love Song; she also won the awards for Choice Female Hottie, Choice TV Actress Comedy, Choice Music Group and Choice Music Single, for "Who Says"!

Why is Selena the current "it" girl? Just ask The Bieb.

"I feel like she's relatable to a lot of different teenagers," he gushed to MTV. "She's kind of girl-next-door; she's real cool. She's very nice... she's a very nice girl."
