Who dumped who in the split of the century? Justin Bieber and Selena Gomez seemed like an unbreakable pairing, but they have indeed broken up -- and sources say they're not together again yet. What exactly went down and why can't they make it work?

Biebs and Sel split near Halloween, and he was spotted hanging out with Victoria's Secret models at the Victoria's Secret Fashion Show where he was performing. This didn't sit well with Gomez. However, the pair did meet up last night (Nov. 12), which led Beliebers, Selenators and Jelena supporters (all in all, a fierce bunch) to believe that a reconciliation may be in the works.

Not just yet, says TMZ. The site reports that it was Selena who ended the relationship and that while they did meet up to discuss the factors that led up to the split (said to be a combination of scheduling problems and Sel's trust issues), the duo are still broken up. Apparently, nothing was resolved and they're not back together yet.

Sources told TMZ that Biebs is inwardly torn, because he's still smitten with Selena -- but he's also an 18-year-old guy, so he wants the freedom to play around a little. While nothing happened between Bieber and Victoria's Secret model Barbara Palvin, TMZ notes that he's enjoying the attention he's getting from supermodels. Dude, can you blame him?
