So many couples can’t seem to find the happy medium between a bored lack of spark and fighting like cats and dogs.

Based on several stories from the past year, it sounds like Modern Family’s Sofia Vergara and her fiancé Nick Loeb are in the constant drama camp. Back in September, when Sofia had that major wardrobe malfunction with her Emmys dress, Page Six said her fiancé was not much help and was just annoyed by the whole thing.

It's possible Page Six tapped into the same sources for this new story, which paints Nick in a bad light after an alleged "heated argument" between the couple on New Year's Eve in Miami Beach. As one witness told Page Six: “Nick appeared to get really angry after Sofia took a picture with a stranger, and started screaming at her. Nick had to be pulled off Sofia by security. Her dress got torn in the melee. This happened right in front of everyone in the VIP section."

The witness continued by saying four security guards grabbed Nick and threw him out of the back door of the club, with Sofia following behind. Apparently they both went back to their hotel, so it sounds like they are still together.

Sofia and Nick have split and reunited "over a million times" a source told People back in May, when they were in their latest "off" phase before getting engaged. They were described as an "argumentative pair of opposites" and when they split at that point, the source called it a "relief."

It sounds like they both have tempers. They are either a perfect match or a nightmare in the making. Kind of like most of the other celeb couples we know...
