Bieber back together with Gomez?

Are they or aren't they?

Justin Bieber apparently celebrated Independence Day with his on-again, off-again love, Selena Gomez.

The proof? This.

The caption? #Heartbreaker. Which is also the title of his new single.

So either they are a couple again, or it's a really savvy marketing move.

Happy post-July 4th, everyone!
