In case you were confused...

Selena Gomez made her feelings pretty clear during a show in Fresno on Sunday.  A fan was holding a sign that said "Marry Justin Please", and she grabbed it, crumpled it, and tossed it.

In related news, Selena told the new issue of "Marie Claire" magazine that she's dating. "I've been having the best time.  But I don't trust anybody, so dating can only be fun if I know I'm going to have fun."
