Selena Gomez Reunited with Justin Bieber at 21st Birthday!

Since splitting up late last year, the former (or current?) flames have kept the media guessing whether or not their relationship is really over. Bieber made headlines this summer after it was revealed that his team banned Gomez’s music from his photo shoots, and Gomez cut off an interview recently after a reporter mentioned Bieber.

So, though they don’t want the other party mentioned in their presence, they can't quite stay away from one another. Ahhh, young love.

Our guess? It’s definitely not over between Gomez and the Biebs.
