If Justin Bieber is trying to get Selena Gomez back, he's doing a pretty terrible job.
Gomez, 21, isn't falling for Bieber's tricks anymore, and she's determined not to enter into a future relationship with her ex-novio.
Sorry, Bieber, but Gomez apparently thinks your gimmicks are "stupid" and "childish."
Good for you, Selena! We're happy to see you moving on!
