Justin Bieber and Selena Gomez

We’ve been struggling to keep up with the on-again off-again romance between Justin Bieber and Selena Gomez, but it seems as though this cute young couple may have split for good. Just weeks after reuniting, Justin and Selena are thought to have had a huge row while celebrating New Year's Eve together in Mexico. Selena apparently confirmed the news to friends while attending the Golden Globe Awards. Neither has commented publicly on the break-up reports.
