Well, if they like each other they could just be a couple, but you now "Hollywood-couples". They would break up someday, and Selena or Justin would write a song about it and the song would be a hit.
well, we may not like. but its her life. we dont exactly get a say in it. and she doesn't get say in ours. so we should support her choices. besides, Justin may be a really nice guy. after all we dont know him. and it isn't fair to judge him without knowing him at all.
Selena is like 2 years older than Justin. Plus, I heard she got punched by a Justin fangirl. She doesn't deserve the abuse, so she doesn't deserve to be with Justin.
