They've been back, they've been forth and now they are apparently together again... with a major catch.
Sources confirm that Selena Gomez and Justin Bieber ARE back together, as evidenced by the photo of the couple on July 4, the date on which Bieber allegedly made a promise to Gomez:
He would stop acting like such a douchebag.
Ever since the pair split in late 2012, Bieber's behavior has noticeably changed.
He's driven around recklessly (a lot), he's got into screaming matches with his neighbors, he's peed into mop buckets and cursed off Bill Clinton.
